I am new to gaming, having only bought a PSP in April, but soon had a load of fun curtesy of Wipeout Pure. I was never brilliant at it but somehow that didn't matter - there was enough gameplay to keep me occupied for hours.
When I saw Pulse was to be released I immediately put it at the top of the wish list, and rued the fact it was delayed 3 months, but the wait was worth it.
This time round the graphics are excellent (They were not exactly poor with Pure though) and on a few tracks you almost feel your sense of balance going askew as the track really does undulate at great speed. The hexagon system already described took a bit of getting used to, but at least it forces you to attempt events you may have ignored on Pure, just because it was convenient to do so. No way can they be avoided here, but you may surprise yourself as to how well you do on events you thought were unbeatable.
Having played the two games, I would say this one takes a little of getting used to. It might be just my inexperience, but the ships on this feel a little more 'twitchy' which means tighter control is needed when cornering. Something that can be adapted to within a few races. The only frustration (in a nice way - it will get you screaming at the screen!) is that you do not get rewarded in race mode if you are in the lead and have had some good clean laps - the opposition seems to always be tight around you thus the frustration when you get obliterated with weapons :) The pay off is if you are not in the lead you rarely find you have much time to make up, so wins are always possible.
Weapon use has increased. Some are useful, others I have found don't really add much, but are useful to absorb, because believe me - in race mode you will need them.
Overall I am having a great time with this game and would recommend it to those new to Wipeout, but also to those who have purchased Pure. There is enough new or adapted content to keep the concept fresh. I am now just keeping an eye open for the promised downloads to enhance what is available.
