AC-III, easily will keep you entertained until Christmas.
Just polishing off another ME2 save ready to play ME3 with the Omega and Leviathon DLC. I do like this type of game which gives multiple choice on different outcomes in-game, compared to those that have a set ending. Not disliking them games, those are good too.
And then i move back onto Skyrim with the DLC packs available from there. Can't wait really.
