Not a patch on Eye Toy 2, so if you are thinking about whether to get 1,2 or 3, dont get 3! I have 2, its great fun, havent got 1 so cant comment on that.
Problem is, there seem to be less games compared to 2, the games are less inventive and so much harder to play that it seems to be random who wins. Crucially, its also very difficult to actually choose which one to play, you select from among 4 or 5 general categories and then seem to get them at random so if there is one you want to avoid, or play, tough luck! Maybe there is a way of choosing but I cant find it.
Get 1 or 2, but not this. If you have 2 and are looking for variety, I'd say spend your money on something else, there are other Eye Toy games out there.
