I keep trying to play Sim City 4, because objectively it's the most well designed, best working sim city, and yet I can never get into it. There's all these "network add on" packs to get things working their best, and I can't stand the design of the game, how it splits everything into regions. I realize the region concept is a more sensible view of how a city actually works, but it's not as fun or elegant as Sim City 2000. Perhaps if you could easily scroll between regions it wouldn't be a big deal, but that's not the case.
I want someone to make a complex, more modern, well modelled Sim City, that's still a bit on the scaled down side. I think I kind of want a Sim Neighbourhood game.
