We've got that Lego game Cod, it's good isn't it?
The thing I like about it is I insist the boys set it up themselves - takes about 20 minutes, then I play (if they insist!) but the game only takes about 5 mins
But don't whatever you do buy a copy of the "Lego racers" game, assuming it's similar. It's not - it's rubbish, and very very boring (even for the kids )
