I would have liked more "modern day" sequences where you play as Desmond, I guess there's going to be a few more games in the series to play out that storyline though, kind of annoying how in the "real world", all that happened was escaping to a hideout, using the Animus 2.0, setting up some security switches, then having the place raided and leaving for another hideout.
Ezio's story made up for that though, and it continues in Brotherhood, very tempted to buy that now although I think I'll wait for a price drop
