This game is a lot smaller than games like Skyrim but its quests are of high quality and really entertaining. Combat is a bit hard at the beginning but quickly becomes easier and fun. You can form teams with up to 3 NPCs and unlike some other games you can rely on them to aid you adequately in the game.
My first 4 hours of play of this game were absolutely tedious. 1) In the first 20 minutes I had to exit the game 3 times and reload because I got an infinite load screen. I have to replay 5 minutes of game each time because the game doesn't let you save when you want. 2) Most of these 4 hours were actually not spent playing but rather watching cut scenes. These were nice cut scenes but I bought a game not a movie. 3) The game is very unforgiving but at the same time does a very poor job of giving you opportunities to hone your skills. So you just end up dead all the time or without lock picks and your last save was like 5 minutes ago..
