A great bargain for lovers of flashy visuals and great gameplay!
7.5 is a joke, come on.
Wipeout HD is a real good bargain, you get a lot of great gameplay (single and multiplayer) and astonishing visuals for a download title. Heck it even looks better than most normal retail games in that sector.
And the fact that most of the stuff in the game comes from the PSP versions isn´t that much of a problem, cause believe it or not there are a lot of people out there, that never played the PSP versions!
The difficulty is really really hard, but there is a autocorrect feature that guides the player along the racetrack very well and unobstrusive. But be prepared to race some events a dozen times before beating them, cause most of the time, a second can make all the difference!
All in all Wipeout HD is a must buy from the PSN. One of the best titles out there on the sony download front.
