Summary: For me, this is by far the best XBLA game I've played. There's a ridiculous # of fun single player levels, and you can see your world rank on each one. For multiplayer there's a mario kart clone, and death match. In all honesty, this 10$ game is more fun than nearly all full fledged 360 games.
Summary: Gripshift is an amazing game, but the 360 arcade version is not as good as the original PSP version. The controls feel a bit looser. I am biased because I have played the PSP version, but if you haven't played it, by all means buy the arcade version, it's well worth the MS points.
Summary: OXM has really been going downhill lately with their reviews.... Or they have a review instead of a cover story, like their COD 4 issue... This game is friggin amazing! I found out about it first on PSP and at first was skeptical but once you get used to the controls, and focus on different (or multiple) goals each race, it is amazing! Super monkey ball with cars....but better.
Summary: This game is best described as "Sonic the Hedgehog" meets "Mario Kart". If that isn't addicting enough for you throw in live support and 120+ levels and you've got gaming gold. The only flaws I've found are the lack of local multiplayer support and the absence of a level editor (found in the psp version). Both of these could be added as updates later on (c'mon sidhe!) not that I'm getting my hopes up.
Summary: This is a great game... online play (when you find someone) is great. just wish it had local multiplayer (split-screen)... that would had make me give it a 9, because it's just sad that I can't play it against friends visiting. but otherwise... very much worth the 800 ms points.
Summary: "isn't worth the points"??!?!!?! I imagine OXM would much rather shell out $60 for Halo 2.5 than $10 for a truly original game like GripShift. If you're looking for something completely different, give this game a try. It has more replay value and fun than most games 6x its price.
