I am admittedly a huge batman fan and ever since finishing up Batman Arkham City I've been wanting to find something to scratch the itch to play through as the dark knight. Lego Batman 2 definitely fits the bill. It's got actual voice-over work with its own fun story that is enjoyable for adults and kids alike. I was pleasantly surprised by just how big Gotham City is and how much there is to explore. The hours will fly by just driving/flying/running around just messing around with side activities or hunting for collectibles before even touching on the main storyline. The bonus is you get access to a huge roster of other characters other than Batman that each have their own unique powers true to their characters. For example Flash has super-speed and Superman is of course invulnerable and can fly, has heat vision, use x-ray vision, has superstrength and has ice breath. The icing on the cake for the fans is the old-school Superman theme music that plays whenever you take flight. There's a lot of fan service to DC Comics fans both old and young that really adds that extra layer of charm that you don't always see. There are some things that are a bit annoying like camera angles that aren't always the most convenient etc., but they are by no means going to ruin your experience of the game.
Point is, if you too are a Batman and/or DC Comics fan looking for a fun game to play regardless of how old you are then Lego Batman 2 is a great purchase that I strongly recommend you pick up.
