Some games are about fast reflexes. Others are about quick thinking. To win at LightBike ($0.99, iTunes link), you're going to need both. Sure, the game is a blatant rip-off of TRON, the 1982 science fiction film that spawned quite a few video games itself. And, LightBike's graphics are far from outstanding. But the game is all about getting a rush from near misses, crucial last-second decisions, and lucky breaks. LightBike is for gamers who like intense, fast-paced action.
