I just picked up this new Lego Batman game last night and it is amazing. It's great to finally get a Lego game with voices in them especially when they got the voice talent from most of the shows. I usually don't play much in the DC Universe, I prefer Marvel, but I think they have a really good story-line developing. Mostly I play Batman Arkham Asylum, Partypoker and Call of Duty but some how the Lego games always pull me right in.
I think it's the kid nature of the Lego games that get most of "hardcore" gamer's because of their simplistic play style and great puzzles. The fact that you can play the Justice League and then some is a cool idea also. The attacks of the Green Lantern are hilarious and the villains and heroes one-liners keep the humor going. If you haven't played these kind of games before, go get them! They are terrific, and they continue to bring more and more out.
