Ridge Racer 2 is essentially the PSP launch title, Ridge Racer, with onlyten new tracks (we're really not kidding about this folks). That doesn't mean it's a bad game ... it just means it's a bad deal.
That is, until now. UK PC World stores will give you the title for a mere £0.97. You're getting a full game for almost the same cost as the free downloadable demo. We say: deal.
