(This one looks good, had to add it, because I have never played CitiesXL, and will give them the benefit of the doubt.. Some version of Cities XL look alright.
I have to admit, Cities XL looks interesting, and as I will definitely be buying Cities Skylines (baring some sort of Sim City 5 esque deviation from what the fan base is expecting).. Cities XL also looks kind of interesting now that i've searched for more images..
The problem I have is when a skyline develops incorrectly.. you get a ton of huge skyscrapers, there doesn't seem to be a central CBD, and there are way too many skyscrapers for the city's actual size. I really don't like playing games that have that kind of issue, and I hope "being rewarded with a taller skyline" instead of "getting a taller skyline for doing nothing" becomes more of a them.
Like I said before, EVERY SINGLE story increase in building height should correspond with a formula that involves:
1. Population
2. Strength of economy of the city
3. Interconnectedness
4. Education Quotent
5. Income
6. Land value
7. Environmental factors
8. Proximity to Mass Transit and transit, including ports, airports, train stations, bus stops, subway lines.
9. Cities total industrial/commercial GDP
There aren't very many cities in the world (outside Brazil) that have skylines that are a bunch of mid-sized residential towers.. most cities in the world you have to have a VERY large city before you start getting any skyscrapers, and those skyscrapers are always in a cluster, or multiple clutstered areas.
This "concept art" of Sim City 5 got it right.. a gradually increasing skyline centered around economic forces, causing land values to support taller buildings reaching an apex.. which is NOT what we find in most "city building" games to date.
I have no problem with "multiple CBD clusters" as is displayed in Metropolitan Areas such as Minneapolis/St. Paul, Duluth/Superior, Los Angeles (with a lot of smaller clustered CBDs and high rise areas surrounding the central CBD) - New York - Midtown and Uptown, London- Canary Warf and Downtown, etc. etc.. It's just that CBD "clustering" is a real thing that real cities do, and a number of factors should be incorporated.
Getting buildings of 4, 5, 6, + stories too early in a small looking city is just so goofy and fake looking.. like I said, there should be a formula that uses the above factors, and only rewards taller buildings (be they residential or commercial, different rubric could be used) only when a player's city reaches a certain size and stature.. that is a fundamental part of the fun for most city building fans, including myself.. and it is often an easily "overlooked" element of the simulation.
