Fantastic game. Everything we've come to know and love from a Lego game.
The levels are linear, get in, smash stuff up, get out.
The city is where you do what you fancy, bit of a race, help a citizen, battle a bad guy etc.
Lots of lovely characters to buy with your studs even if you don't really need to use most of them.
If you've played Lego games before you know what you're looking at. It's a good game with plenty to do.
I've got the Xbox 360 version. It's very glitchy. Sometimes I'll be battling a bad guy and he simply does not suffer damage. Sometimes a level will just freeze. At one point I turned into a random characted called 'Citizen' (which doesn't even exist, you can't buy him!) and couldn't access any misisons. This happens about once per day of play.
Turning the Xbox 360 off and on again sorts all of these but it is a bit of a killjoy.
All in all, definately worth a play but I probably won't play it again because of the glitching,
