Remember Excite Truck? Now that was a fucking great game. OK, now imagine Excite Truck, only with dirt bikes instead of trucks. OK, got it? Now add in a fairly deep career mode (65-plus events!), blander tracks (you'll miss the sphincter-puckering drop-offs from Excite Truck), and six-player online competitive racing. Welcome, Nintendo, to online gaming! We've been expecting you for, oh, the last 10 years or so. Nice to have you! And voilàyou've got Nitrobike. The graphics aren't nearly as polished as they should be for a second-generation Wii title. But the racing action is solid, if overly familiar, fun.
