An upgrade to an XBOX now means there are a load of PS2 games for sale, starting with these 2 great games: Destroy all Humans 1 and 2, 5 star games scored 9/10 by PlayStation magazine and have given my kids months of fun.

I guarantee you that if you buy these games your kids will never look at policemen or cows the same way again. I can't guarantee whether that is a good or a bad thing, however.
Please buy them, they liked to be played ...
