I'm sure many of you played the original Hydro Thunder on the N64 and at arcades and if you liked that game then the new one on XboX Arcade is totally worth a download (there's a demo too). I was a bit worried that they'd screw it up, but they stayed true to the roots of the original which is absolute mayhem on the water with ridiculous amounts of speeds, shortcuts, boosting, and crazyass maps. It's really fun. The AI in the later levels when you get to the Extreme boats get a bit difficult though and hitting the perfect combos of shortcuts and stuff is the only way to win really.
