Some Lego-based games I would definitely look forward to:
Lego Alien. Ability to play Ripley, Hicks, Newt, Ash, and (of course) the Alien in its various stages of development.
Lego World of Warcraft. Well, why not? (Depending on your current video card, you’re almost playing this now anyway…).
However, I suspect that Lego 2001, A Space Oddysey and Lego Apocalypse Now would be unplayable.
