The Eurpoe market never seemed to bad for mega drive games or saturn games. Dreamcast games on the other hand was a diffrent matter. And the cases for Dreamcast games were fuckin awful. You could look at them and they'd break.
I will always love the Saturn and the Dreamcast for these (European) reasons:
Saturn: Panzer Dragoon 1,2 and saga, Bug, Duke Nukem (Death Tank), Street Fighter Alpha 1 and 2. etc.
DC: Skies of Arcadia, Crazy Taxi, Sonic Adventure 2, Street Fighter Alpha 3, Marvel vs Capcom, Sega Bass Fishing etc.
