I managed to overcome my gaming apathy enough to finish Assassin's Creed 2 with all achievements, in a total time of around 30 hours. One of my favourite games from 2009 without a doubt.

Don't know what to play next; I was enjoying the particular style of gameplay and can't muster much interest in something else. Perhaps I should replay the first game, it's been 2 years since I completed it. Hmm.
