Lego Batman 2: DC Super Heroes Complete! It takes roughly 20-30 hours to get the 1,000 gamerscore. Not too difficult and features the standard achievement list found in most Lego games of the past.
It's probably the best Lego game on the machine, but I'm a little burnt on Lego games since I've played them all except for Lego Star Wars III: The Clone Wars.
What's changed from the 1st Lego Batman?
Open World of Gotham City (not a ton to do in the open world, but it's where you will find the majority of the gold bricks, animal riding, carnival games, helicopter and boat checkpoint races)
First Lego game where the characters have voices (very well done, I might add)
Features a ton of DC characters not found in the Batman series.
Superman absolutely steals the show since he is just awesome to use (flight, heat vision, superhuman breath, X-Ray Vision and superhuman Strength) and the Superman theme song is played every time you fly in the open world hub, which made me smile every time. Superman and the other characters that have the gift of flight make the helicopters pointless.
A lot to collect: 150 Minikits, 250 gold bricks, and 50 civilians.
Rating: 8.5 out of 10
It's a must have for Lego fans and probably the best Lego game made to date.
