You'll run through the 15-chapter story of LEGO Batman 2 in about nine hours (probably a lot less if you don't methodically smash everything like I did and get distracted by side stuff), but then you'll replay levels for more studs (in-game currency) and to find collectables such as mini-kit parts.
Of course, the story is just a tiny sliver of any LEGO game.
Fresh voices are used for most of the other characters, but the new takes are welcome. Among these actors is Superman: The Animated Series' Clancy Brown reprising his role as Lex Luthor. Robin fanboying out over Superman, Vicki Vale's newscasts, and Lex trying to convince Joker that killing Batman is a good idea - these are brilliant moments we would've lost without the excellent actors. While the silent LEGO games have always been funny, LEGO Batman 2 is able to move beyond shrugs and grins. For the first time in LEGO history, LEGO Batman 2 packs a full voice cast to tell its tale. “It's a focused story that's entertaining from start to finish, and part of that is thanks to voice acting.
