Nice to see somebody else that appreciates Icebreakers! That game is the single reason I don't have my 3DO anymore.. My mom found it in my collection, tried it, and laid claim to my system a few years back. I still haven't been able to get it back from her!!
Return Fire is a brilliant 2 player game! I can remember spending way too much of my time in college playing this! The sequel wasn't quite up to snuff, but the first was pure gaming bliss!!
What about Shockwave? I remember being more impressed with this than the early releases of Wing Commander. Shockwave was a bit more arcade like, but still a great game.
And Need For Speed, the reason I bought the system in the first place! Once I saw the FMV of the cars, it was just a matter of time before I had one!! Spent many an hour playing this one too!!
Don't forget about Road Rash.. Killer soundtrack and bikers with weapons. What more does a game need??!!
