There are a few good games for the 3DO. Picked up most of mine for $1- $3. Bought my 3DO from Best Buy when they were clearancing them out for $50. I was a cheapass back then too.
Gex (great platformer)
FIFA (still a solid soccer title)
Road Rash (good)
StarBlade (decent)
Star Fighter (decent)
Cannon Fodder (all time favorite)
Samurai Shodown (rocks)
The Horde (another good one)
Street Fighter 2 Turbo (rocks)
Star Control 2 (solid)
Battle Chess (decent)
Panzer General (played the hell out of this one)
Doom (good translation)
Wolfenstein 3D (good translation)
PGA Tour 96 (solid golf title)
PO'ed (oddball fps)
The Perfect General
Star Wars Rebel Assault
Myst (good translation of PC title)
Way of the Warrior (Bad, way Bad)
Flying Nightmares (could never figure out the control scheme)
Out of this World
Alone in the Dark
Escape from Monster Manor
Dragon Lore (3 disc) (bored the hell out of me)
Shock Wave
Shock Wave 2
Immercenary
Space Ace (good translation of arcade)
Dragon's Lair (good translation of arcade)
The Daedalus Encounter (4 disc adventure with Tia Carrere) (got stuck at very end, pissed me off abit)
Just hate the limited save space on the system. Might have to set mine up again.
