Sometimes when we start up a game with branching story paths or "evil" character options, we'll get down with our bad selves and go for the dark choices, intent on violently slaughtering the goody-two-shoes right off the "light" side. With Guardians of Middle-earth, we don't think we'll be able to do that, though.
Perhaps it's because we're invested in the lore of Lord of the Rings, because we've spent years devouring the books, films and Trivial Pursuit board games, and we've rooted for Frodo, Gandalf and the good guys to win the whole time. Choosing to play as Sauron now would feel dirty.
That said, the first-ever gameplay trailer for Guardians of Middle-earth makes each side look equally cool, and it promises the game will launch this fall, for XBLA and PSN only. Go Gandalf! Really, go -- Sauron's like right behind you.
