It looks fun. As fun as a game can look from screen shots, but still fun! And I'm 34, so sod it. If everything goes to plan, I think ZombiU will be the only 'adult' game I have on the Wii U until, well I don't know. It's a nice change.
Still not got around to playing Lego Batman 2 since I bought it on Steam for about £4 the other week!
