I've only ever owned RCT3 and No Limits but I definately prefer No Limits for some obvious reasons - The graphics are alot betterIt's a lot smoother if you know what you're doing, it's not necessarily easier especially when you first get it but you can create a much better coaster.I was quite confused by No Limits when I first got it and got frustrated with it and used RCT3 but now I basically use No Limits whenever I can :)This is becoming a long reason so I'm gonna shut up now Bye bye
