I've still got an fz-1 and an fz-10, it's not a system i play anymore though, road rash, gex, blood angels, killing time, street fighter, wing commander 3, return fire were all decent games on it back in the day.
Lots of shit fmv games and just shit in general games on it though, you couldn't give them away 10-15 years ago, nobody wanted one, i didn't pay more than £30 for either of mine.
The 3do card you could stick in a PC must be rare as shit in a cuckoo clock now but practically useless TBH.
Pretty sure there's no copy protection or region lockout either, so easy to burn iso's if you want to play the library, i've never tried though.
Don't think there's one proper shooter on the system either.
