A perfectly good engine that has some fairly unimpressive stabs at a game thrown into it. Possibly worth owning for the hilarity of needing between 70 and 80 seconds to quit (as opposed to hitting 'Esc' and clicking on 'Quit') : http://www.youtube.com/watch?v=gwOvuY0UbFM As GOG are relaunching and trying to shake the values that gave them their acronym originally, I can think of no better game to help them with this than Assassin's Creed - a game that is neither old nor good.
