Saved it before the poker game so I got to see both endings, and the only gripe about this game is twofold.
First, the story didn't have enough in it to want to either save the friends or kill them and stay with Citra. It was a hard decision because I really didn't care either way.
Secondly, Vaas should've been the head guy. I didn't really have any strong feelings towards Hoyt because I didn't really know him or see him like I did Vaas. It was fun to kill Vaas, no real emotion after killing Hoyt.
Gameplay was fantastic. I got all the radio towers and forts on the initial play through and now I'm going for all the hidden stuff and side missions. Tons of hours of gameplay as it took 50+ hours to beat it and now I have a lot more to play.
