As said by Zombiegangster...modders are on all platforms. PC would be the better option in my opinion, with specific servers for modding, etc. and modding on PC can actually be fun for all people rather than just the one person using hacks (like zombie mods, custom maps, etc.) as far as console gaming goes, both XBOX and PS3 are full of ISO/GDU Modders, if you want a new console, now is a terrible time to get one as next-gen consoles are just around the corner...
