I´m not talking about graphics, sound and that kind of thing...just the fun you have while playing it.

If you played all the NES Mario games and Mario World, how´s NSMB Wii compared to them in the fun department?

I would rate them like this (fun-list):

1. Super Mario Bros. 3
2. New Super Mario Bros. Wii
4. Super Mario Bros. 1
3. Super Mario World
5. New Super Mario Bros. DS
6. Super Mario Bros. 2

Mines almost the same as thornstrom's
1. Super Mario Bros. 3
2. Super Mario Bros. 1
3. New Super Mario Bros. Wii
4. Super Mario World
5. Super Mario Bros. DS
6. Super Mario Bros. 2

Haven't played NSMBWii extensively yet (but will tomorrow), but from the few hours I spent with a review copy it'd go something like this:

1. Super Mario World
2. Super Mario Bros. 3
3. New Super Mario Bros. Wii (Though the hilarity of it all gets increased tenfold when playing multiplayer since you're almost constantly laughing out loud)
4. Super Mario Bros. 1
5. Super Mario Bros. 2
6. New Super Mario Bros. DS

Honestly, I think it's the best.

NSMBWii is definitely in the same league as SMB3 and SMW; and much better than NSMBDS.

As far as being fun, NSMB wins when you are playing with others. By yourself its still pretty close though.

NSMBWii/SMB3

SMB/SMB2 (Lost levels)

SMW

NSMBDS

NSMB Wii is the best so far. Mario fun + 4 players = Win. Too insane having all four players with costumes and a yoshi of their own lol

As long as it's better then NSMB DS I'd be quite satisfied :)
