I rented this game a while back, and completed it in one sitting in co op with my brother. Then, we got 100% in the next sitting. It was quite fun and enjoyable, but just too easy and short to justify a full purchase.
Yeah the lego games really are surprisingly fun, good fun if you can get them relatively cheap. I confess I bought the Lego Star Wars: The Complete Saga recently for AU$30, and it's great, easy, cheap fun - good when you just really can't be bothered thinking about your gaming, or getting the blood pumping.
Personally while I enjoyed this I thought that the Lego Star Wars was better between the two, all the vehicle missions in Lego Star Wars helped break up the slight tedium of walking around in the levels. Overall it's a great way of doing movie based games & quite an entertaining rental for all of them. They're short to play through a few times on each level but with the Lego Indy they seemed shorter than the Lego Star Wars games, plus the Lego Indy AI was a bit troublesome at times where grenades would be from off screen or the 2nd character you can play was in the way of where you were swinging/jumping too forcing you to fall off & die. Based off what I've seen for Lego Batman, it looks like they are constantly evolving with some of the design so it should be a lot of fun, especially with the ability to play through the levels from the Batman bad guys/girls perspective on the story missions.
