I've been playing for 2 days & I'm at about 40% completed in regards to game progress, unlocked characters, and red brick cheats. There are spoilers.I love this game! I saw the trailer, so I knew Luthor & Superman were in it, but that's not even the half of it! I've unlocked Vixen, Black Canary, Superboy(black t-shirt clone Connor Kent Superboy, not teenage Clark), and a few Batman villians that I became familiar with from the first Lego Batman(I'm not a huge comic book reader, but I loved the DCAU shows from Batman:TAS to Justice League Unlimited). I know Flash & Green Lantern will be unlockable because certain cheats can't be unlocked without them.The icons are a little smaller so if you have bigger fingers, you'll have to use your stylus during free play. Also, I unlocked the X2, X4, & X6 red bricks already so if you were hoping for a challenge in stud collecting, you might be disappointed(although you could just leave it off).All in all, I'm enjoying this more than the first Lego Batman, which I've played over & over again for months.
