I've heard of all of these; haven't played some of them like Chibi Robo though (but that little guy is sooo cute!)

I'm surprised to hear so many people haven't heard of him actually.

chibi robo and advance wars. Never heard of them.

Golden Sun - yes loved the games on gba
Fire Emblem- of course best srpg for me
Pilot Wings-only played n64 version
Wave Race-yes wave race blue storm was best racing game on gamecube
Advance Wars- never played them to much but my brother as an advanced wars freak-
Chibi Robo- heard of never played
Punch-Out- played them all
Earthbound- played earthbound on snes
Brain Age- never played but definitely heard of them
F-Zero- need a new f zero hopefully not as cheap as gx

one, Chibi Robot

I knew all of them, but I have no idea what Chibi Robo is actually about.

Advanced wars was painfully addicting in my younger years. As for brain age, I have a vagye idea of what it is but I'm not sure how. So... 3-4?

Three of them
