@Maurith - Donkey Kong and KI were both really good calls!

@Jayvee - I only played the original. Is the latter a new game or a remake?

Earthbound (1983) and Earthbound (1994).

2009 Punch Out is more like a reboot, it has modern graphics and the core gameplay is the same, but there are some new bosses added to the campaign, the final boss is changed and there is DK as a secret boss. I'd assume it's pretty different xD

I would suggest adding Area 51, there's 2 of them.

@FallenGrace what about Mario Golf (64 and GBC) and Mario Tennis (64 and GBC)?

@Zguvat - That's a good call. I used to love the arcade light gun shooter.

@Geno123 - Are they different games or just different platform releases? Never played them.

@FallenGrace It's the same case as the Genesis and Master System Sonic games, in addition the GBC games have a JRPG style story mode, something that the 64 versions don't have.

@Geno123 - That I understand, both added thanks! Mario Golf doesn't even have a different cover here XD
