I've played nearly all the Lego videogames on xbox and absolutely love them! I can't believe how far the games have come in terms of the area outside the levels. Gotham city is huge and there's so much to do- miles better than the college in Indiana Jones or the bar in Star Wars!
This game definitely does not disappoint, if you're a fan of the lego games then you will love it. The levels are interesting, the character abilities are really clever and the video clips are hilarious. There are the usual annoyances that come with lego games- trying to get Superman to fly where you want him to is frustrating as hell, there are the occasional glitches which mean you have to restart levels- but overall this game has very few faults.
I found the game to be not particularly difficult (compared to lego marvel!) which makes it better for kids but at times I feel it could have benefited from a bit more of a challenge. For example, when you're defeating the boss villains scattered around the city it's just a few hits, win, move onto the next one. Some aspects of the levels are quite repetitive and it would have been better if they mixed it up a bit. Same story in the city when you are saving citizens and finding gold bricks as they're all hidden in the same places.
Overall, loved the game, totally addictive and I still had to complete to 100%- but loses a star because it's a bit easy and repetitive. Not as good as Harry Potter or Lord of the Rings!
