I am making my own map for a Tokyo inspired city.

I own and have played both games, here are my thoughts.

CS:2 - I like this because alot of mechanics in the game just work, like the roads. Also graphics look amazing, which will help me build a realistic city. But I have experienced the performance issues, and the bugs which definetely hinder the gamplay. Another thing to consider is the region packs, CS:2 comes with a region pack for Japan. It's not hard to download mods on my computer but just makes the process of zoning alot easier.

CS:1 - I like this game because I could 100% fill the entire map and get to 1M pop on my computer. The only thing is the mechanics and graphics are alot worse in this game. I would have to download heaps of mods to have the road building mechanics working like they do in CS:2. But at that point I may as well should just play CS:2.

Another thing to consider is I am making a map. I am unsure of what game is easier and better for making maps.

Do you guys have any other factors I should put into consideration or advice?
