Well I guess thats paradoxs usp (and they realise they need to keep it or they will get outmarketted by ea/activision). They stay true to their roots whilst alot of other gaming companies sell out (like by making their pc games console ports). I am glad they do because paradox is easily my favourite gaming company. Honestly I was so happy when I found these games existed. Thats probably why I own all their games and in fact I own quite a few of them twice. I just buy their games now on principle because they have earnt my trust and I want to support them. I think TW series has sold out for mass appeal. And in the process they please nobody. They might sell games by putting a ton of money into marketing rather than development but its a short term strategy imo. TW like you say is just gfx and battles now. The rest of it has gone backwards.
Idd.. its better to keep a niche and be praised for it than just become another mainstreamer for $. this however means that the community needs to support the company in order to secure more games.. they need $ to make games afterall, but well with the way they treat the community most pay with a smile
I have gone so far to actually not buy games thats pure ports from consoles.
But the community here make it even better, to state some examples, I can without doubt say that the most fun MP games I ever played (all games) was EU3 MP with alot of people, the community here is friendly, mature and they wanna interact and make a good expierence.. I can already see CK2 being massive when it comes to MP, I am looking forward to it.
