Sorry for not replying to this sooner, been really busy and haven't even got to play the game yet. I think I'll go with what T Wrecks suggested and just play it w/o mods, then see what I want to improve/add and stuff. I will look at all the mods you other guys linked though.
I'm about to get SimCity 4 and was wondering if there were any mods that I absolutely should have. Also if there's other things that improve the game and generally the best things to have I guess. Sorry if this is the wrong board to post this in.
