I just started Assassin's Creed and I'm just past the point where the first town is being threatened by the "other guy" (haven't played it enough to know his name) and I just did the high dive into some straw. That's it. So I've got at least a little bit of enjoyable play time left with it.
I haven't played any Unreal game in years, but the gaming community that I am a member of (EcS Gaming) has some people that play it. Seems like VERY fast gameplay.
