Like all the other lego games they seem to have fun gameplay to them. I myself am more of a hardcore gamer that enjoys shooting/adventure or racing. But still for the limited time i played it until a more anticipated game came out it was fun! Liked the fact that you had a couple costumes for batman and robin to use to mix and match up the gameplay.
If you liked Star Wars Lego, you'll love Batman Lego. Game play hasn't changed and no online either, but an honest to goodness family game. The puzzles are pretty straight forward, but challenging nonetheless. I will probably buy this game. And that's something that I don't do!
