After playing the game for 1 hour, I gave this game a bad rap. To make matters worse, I gave it a 1 Star PSP review by accident when I thought it said PC (I don't even have a PSP). But after giving this game its due, I am impressed.
This game is a logic game. Some of the things you have to do with the batarang and grappling hooks are crazy. You have to really think parts of this game out. Its challenging and I like that you use Lego bricks to buy things in the Batcave part of the game.
My only gripe (after playing the game for several hours now), is that some movements, such as climbing UP a ladder and jumping to one side or another, are complicated. Its hard to do and I have not figured it out, but I'm not going to slam the game because of that.
Its a good game. Worth $29.99 right now...eh...I'm not going to say, but that's up to you. So if anyone saw a bad PSP review, it was an accident and I'm sorry. This is a pretty good game.
