For the uninitiated,
wipEout HD may be a bit difficult. This game does seem to expect that you've played a game or two in the series before. That having been said,
wipEout is a relatively straightforward game... well, in gameplay, if not in track design. There are a few things to bear in mind if you're trying to manage the game's difficulty...
First of all, there should be no problem finding enough challenge in wipEout HD for even the most die-hard wipEout fan, with new teams (and, hence, new ships), the unforgiving Zone race type and eight increasingly difficult events to work through - not to mention the Online mode, which allows you to play against up to seven other players from around the world. You should be able to find someone out there who can offer you a challenge.
If your fear is that the game will be too much of a challenge, there are things to help you out here, as well. For one thing, you can set the difficulty level or the artificial intelligence of the computer-controlled opponents. If you're finding the competition a bit too steep, take 'em back a peg. As for the speed-only races, where there is no competition but yourself, you will actually see a "ghost-ship" hologram that shows your best time on that race. If you simply work on beating that opponent (essentially, you), as you practice and do better, your time will get shorter and shorter, and eventually you should be able to achieve a Bronze, Silver or even Gold medal in the event.
One thing that some players have trouble with in wipEout games is controlling their ship and keeping it from flying off the track, which costs them valuable time. wipEout HD remedies this with a new Pilot Assist feature that can be activated in the Options menu and will activate when your ship starts to get close to the edge of the track, nudging it back towards the center of the track.
Another thing to keep in mind is that the power-ups can affect the difficult of handling your ship. It's all about speed, but using a turbo boost power-up in the wrong place can send your ship careening off the track. Meanwhile, the Autopilot power-up might not make the best use of pick-ups, but it will give you a few seconds of impeccably accurate piloting - which may be handy for using in that part of the track you always seem to slam into... it's okay - we each have our own.
Finally, in the Race Box mode, you can play against another person in a split-screen game (horizontal or vertical - your choice), so if you are the world's worst wipEout player, you can invite over the world's second-worst wipEout player or duct tape a controller to your little sister's hands and actually beat someone. I'm just saying.
