Yeah, don't bother with old Fusion Frenzy, it's got some real issues on the 360 - slowdown, jittery sometimes, its really best saved for the original Xbox, you'd only be dissapointed. But don't bother with Fusion Frenzy 2 either

- for some reason the XBox was best for these 4 player party games IMO, Kung Fu Chaos for example was brilliant fun with 4 players. The 360 version of Doom is horrible too, I'd still play the add-on version for Doom3 for the XBox, smooth and glitch free in comparison.
At least your getting a solid game for your money with this, I mean I copied my Fallout3 save to my bros 360 to play Point Lookout, and completed it in 1 go, for 800 points they can keep it!. It's just a shame that they feel they have to charge so much, compared to GTA4:LAD, which has hours of good gameplay added, new vehicles, weapons, even multiplayer modes.
