Dragon Age II

This is an RPG game developed by Bioware that's set in the same universe as Dragon Age: Origins and if you have a savefile from Origins you can load it and you will start off at the same level and the same equipment! That was a lie. But it does influence the story in certain ways. Playing Dragon Age II is a very similar experience to the Origins, plus various additions and changes (mostly improvements) so if you liked the previous title of these series, you'll most likely love this one.

Plot
You start off as a human rogue/warrior/mage and you cannot choose another race unfortunately. Now if you played Origins, you will notice a bunch of recurring characters and you will also understand things a little bit more, but it is not necessary to play the prequel to enjoy this game in my opinion. You will always get dialogue choices, which will usually add friendliness or rivalry between you and your comrades, or sometimes will change the outcome of events. There are often some funny options (although they can lead to unexpected results) and you are free to experiment and be a real asshole if you want to - you'll still be the "champion" at the end :]
WARNING: the game might confuse the shit out of you at the beginning, since it's hard to understand the relationship between the separate events and the role of each character in the storyline. Eventually, though, the puzzle pieces come together and you should understand what's happening, so HAVE PATIENCE.
