Well, I don't feel the graphics of the Sims 4 is behind anything. It's different, but it's not poor in many ways (polygons and rendering aside). We've all heard the saying that art is in the eye of the beholder, and I stand by this. Some of the worst looking games have had the most fun and re-playability for me (is that a word?). Whereas some of the best looking games have been as boring as watching paint peel. Albeit, they're beautiful to look at. You may know I'm not a Sims 3 fan for this very reason.
Anyway, I t's not the graphics in the latest iteration that bother me. It's the gameplay itself. It's sorely lacking. This is a caveat I've seen many times as a payoff for graphics. The Sims isn't the only game I play. So graphics are not my biggest concern. Jiggle physics and realism a good game don't always make. I do agree with the rating per se. I feel it will keep away many other caveats. However, if I were to look back to the original Sims game, the graphics aren't where we'd expect them to be today. However, the gameplay by far exceeds what gameplay we see today in this particular genre, and much of that had to do with not being so concerned about great graphics. It was just about having fun with a life simulator.
But I partially agree. Good graphics are nice, but what exactly, are good graphics? Are we talking about the emptiness of Sims 3 with its lack of animations vs the well-thought out psychology of Sims 1 and 2 with Sims 2 well thought out animations?
Personally, the reason I was drawn to the parody on life had more to do with what I could do with it as opposed to what it looked like. I've been playing Skylines for the last little while and I'd hardly say it looks realistic. Yet I'm finding it more fun and challenging to play than SimCity--a game that never appealed to me. I can't put my finger on why that is. I can guess, but I can't say exactly why.
All in all, I'm not against good graphics. On the other hand, the gameplay needs to be there, and it's not in the game we are discussing. But to reiterate, gameplay is more important than graphics. Why? I actually find Sims 4 attractive to look at. The scenery in Sims 3 was also attractive, but there's a reason why I want to see someone else take the reins, and it's not because I find the gameplay in either of those games awesome. They are both extremely poor.
I could go on about what I don't like about both of those games, and there are things I didn't like in the Sims 2 as well, but I will keep it to myself unless someone asks--at the sake of saving myself from writing an essay and others from reading it.
Edit: I played Resident Evil 1 & 2. I still play them. The gameplay has degraded since then, regardless of its great graphics. I also don't want to see things like menstrual periods and menopause. That's getting too real for me and beyond realistic for a game. I seriously don't want to see my character bleed for five days and not die. Sorry. But that's going too far.
wow it's not about "bleed" it's about "reactions" realistic reactions, have a female, angered during her days, make we believe more on her being a "woman", and can be fun have the classic husband trying to understand the woman and failing while she is anger or crying and that things which make the psychic human awesome, or when is the male having is midle age crise where we males normally start to want be "young again" and become complicated too like womans"(is not just womans which have problems over time, you can have more than us but being human is really live in suffer and find way to make that suffer fun is what can make the game special) remember if you are asking for a "true life simulator and not a parody" or childsh game more we get close to real situations better, will be like just a mood to make the character have some behaviuos nothing more.
and about graphics you also can find awesome games which can have both, good gameplay and awesome graphics, street fighter a classic exemple for peoples which love fight games, wow for peoples which love mmo or guild wars, the witcher series, a think many peoples are missunderstood having good graphics with lack of gameplay, as you told we can find both, you can find boring games which good graphics and boring games with bad graphics what is matter is the piece between the chair and the computer

(the programmer) if you have a competent team they can and normally delivery both, a good exemple for what i read is ARK: survival is a awesome game all the peoples which are playing are liking it.
when i speak graphics i also speak about animations that is why have more fluid moving body, characters while iddle don't like robots, it's not just face, face is just for fun if you really want a character which can make you feel he is alive, he must really look alive that is why you have the big majority of games doing that, go look at witcher let the character stand and you see he's breathing, this is a conjunt of animations with high quality graphics, a good animation and graphic team can do that and when adding actions make sure no "short cutes" like maxis are being doing, in the same way i want to see the characters open counters to take forks, taking the spices from the cabins or take the forke which is on the wall if needed, have less "just deco objects" and more interactive ones, at last the ones which make more sense, be able to open window good animations, a good humor which actually match his age restriction which if is teen or m must be threated as T or M, not call T and threat as C or E, like maxis is doing with sims 4.
and i gonna say what bug me more in sims 4 graphics are the octogone objects, you see the new pack?? the candy eyes octogon??? maxis keep pulling more low resolution objects over and over this annoying me a lot in sims 4 that is one of the reasons i stopped to support i don't support lazy companies or game companies which are greedy and for the sake of save buckets in pockets release "sub" par quality products, what sims 4 have is a bealtfull mask(the colors and cartoon) trying to hidden a lot of short cutes(less animations) and bad graphics(low resolution/poligons/bones) and force a AAA game price on it, i could be fine if the game was at last half of the price" to counter the low quality and lack of content" even packs have less content for the sake of "fast release" and again reduce cost and save more money in they pockets, for a non microtransations game the sims series starting on sims 2 , look to much like or even worst in some cases, with the ammount of payed content outside game base, just look at the others games being made and you will see then gonna have in base what maxis love "to make peoples pay" like basic weather or pets and probably generations, the 2 new games being made gonna have basically 3 to 4 maxis expansion packs in base game, that is to show how maxis and ea are being greedy and take advantage the fact which they where the only team doing that sort of game until now which is now changing and as i told i looking foward for that games to see peoples pulling things more interestings, i want to see a life simulator with most realistic possible graphics humans with most possible human situations for us to deal i really want someone step and make the most complex life simulator even see, because this means more challenge and more "connection/immersion in game, like have a couple where the husband or the wife get jailed then the free sim must deal with it having a partner in the jail, explore the most possible humans traits and reactions possible.
something which probably obvious gonna take some more years until but i want games which improve and that is why i prefer a game rated M (17+)because this can help the game touch many aspects and can still be fun and not "a just porn or extreme gore, something with the perfect ammount of realism to give a good ai with many troubles possible for us to explore in game and find good ways to deal.
sometimes i feel peoples are too used to sim and any game which not look lit it will be "creep", if we get that sort of mind then never none can be more "realistic" which to be fair is what can evolve a good life simulator, the more the game evolve the more complext it become, you can't forever don't want characters murder because you are scared, or others things because "you are scared" or feel can be creep, that things are important to have over time, and if you want just a game with minimal things then could be much better have just options for that things because basically the game gonna end being just another the sims which is exactly peoples are not wanting anymore.
