Rayman workout mini-games are really workouts!
I mean that running to the bunny with a exploding present is just wicked!
Your arms will feel like jelly if you do your max speed.
Thats why i recommend this game.
About Madden 07 haven't played it but i see people are quite happy with it.
Madden is probably the longest but has no replay value but Rayman is super fun (I'll be right back gotta go play kinda fun) deffinetly not Need for Speed
I would say Madden, but I haven't played the other two. I think Madden has a ton of replay value with the depth of gameplay options such as Franchise mode. Not to mention the Wii controls are great.
Rayman is pretty sweet.
I don't know about the other games though.
I'm guessing they're like every other Need For Speed and Madden title out there.
At least Rayman has some sort of innovation.
I haven't played Rayman Raving Rabbids or Madded '07, but I would say Need for Speed Carbon has the best replay value only for the reason that racing games never get old, and as a bonus Need for Speed Carbon is an game awesome in the first place even if you don't know the story behind it, like me.
