I hadn't really played any except that one too, and I found this pretty easy to jump into. There's a bit of trial and error involved in some aspects of it, but I found the information you need to know is a lot easier to decipher than in the old SNES SimCity. There are a lot of different views/overlays you can use that show you what's what in a flash. When I start playing it's hard to stop!

The SNES version was so fun. And the Iphone version ( which is htink is simply a port of it)
Its pretty much the same, but a little more dynamic.
I.e you play around with residential zones and build them a certain way to attract a certain kind of sim and play around with taxes to keep out certain types of busieness etc etc. Very fun, but buggy. Give it another month and things should pick up.
