The 3DO is pretty good for the FMV games (clearer than Sega CD but not quite as good as the DOS versions). The CD-I versions of the FMV games is the closest to the arcade that you can get at home (get the Digital Video card and you are good to go). Also on 3DO worth getting are the games:
Star Fighter (I prefer this version to the one Acclaim released on PSOne and Saturn later)
Captain Quazar (why that wasn't ported I will never understand, overhead isometric action game with a funny presentation)
Gex (some claim the PSOne and Saturn versions are better based solely on the FMV cinemas)
Ice Breaker (it is on DOS too if you can't find one affordably on 3DO-it is a shooter puzzle type game, think something like Kickle Cubicle on NES)
Bladeforce (another why wasn't it ported game, 3D flying through a pretty good cityscape and hard as nails)
Killing Time (also on DOS but this version blows that one out of the water-horror based 1st person shooter that had a pretty darn good story)
Dragon Tales (I believe this was the name, it was released by Mindscape and is kind of a FMV based RPG with real time fight scenes, most of the game plays like Myst)
Brain Dead 13 (animated FMV like Dragon's Lair but funnier and entertaining)
Hell: A Cyberpunk Thriller (FMV adventure game, fun little game I thought, just rather stilted animation-worse than Strider 2)
If you are into softcore Adult games, the 3DO is the system of choice here too-Snow Job is one that treads the line but is a good adventure game.
The Nomad is interesting if you play at home a lot but can't access the big screen TV for your Genesis gaming for whatever reason (or are just wanting to beat that level of Sonic or something before bed while in bed).
Jaguar, get these:
Aliens vs Predator
Tempest 2000
Doom
Wolfenstein 3D
That is about it for Jaguar, it was heavy on 1st person shooters, at least the worthwhile games are in that genre.
