Basically, Lego Batman is a blast, and old favourites like the character mixer and the ridiculous costume upgrades only add to the fun. Even though you won't know the scenes this time around, the sense of humour is still infectious, treating Batman as a slightly stiff hero, Robin as an over-exuberant and foolish sidekick and giving certain villains - particularly the lovably goonish Clayface - an appeal that they never really had in the comics or cartoons. And the sizable, larger than life cast helps the game get past the central problem with Indiana Jones - who wants to play anyone else but Indy - by making every playable character a lot of fun.
The only reasons I'm being slightly stingey and 'only' giving this an 8/10 (though still a warmly recommended one) is that a) we still get the occasional bad camera angle issue and b) I've been on the sharp end of several bugs during playthrough, including one where Batman got stuck behind scenery towards the end of a level and one where Catwoman literally disappeared during a climactic battle, forcing me to quit and replay the whole level in both cases. Otherwise, there are a few occasions where single players will get annoyed by the AI - though this really is a game best played with friends or family in any case - and the odd moment where it's just not quite clear enough where you should go or what you should do next.
Still, I'm not complaining too much. Lego Batman is another great instalment in the TT Lego series, and a game that practically any gamer of any age group should enjoy. In fact, it's one of the few games where kids can play with grown ups and you can guarantee that both will have a good time. It will doubtless sell in huge numbers and, frankly, it deserves to.
Possibly the best Traveller's Tales Lego game yet. The scenes and story might not be as familiar as the Star Wars or Indiana Jones movies, but TT has used the extra freedom to create more satisfying gameplay and a long series of great levels.
