Snake plays ok... I can't seem to get very good with him.. his moveset confuses me. It would be silly to buy Smash Bros. for one character though.
Mike, I also saw Lil Mac recently from Punch Out, I CRACKED up!
My two favs are Link and Samus.... (i played many many hours with them on Smash Bros: Melee)... I REALLY dig Ike and Meta Knight as well.
