Wipeout is brutal hard and I could see how that would turn off some fans.
But honestly Wipeout HD is one of the best downloadable console games I've ever played. I mean its gorgeous 1080p at 60fps and the crazy weapon based raceing is just awesome!!!!!!!!! Its all about mesmerizing the tracks and learning where to hit boost pads and when to use weapons / or absorb them for more energy. Overall straight up fantastic game IMO.
