I don't think Smash Bros should be on this list.
Smash Bros is a mix of Nintendo characters, not just Mario characters.
All these other games are Mario-specific.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
