Just beat the game, I put 21 hours 1 minute and 38 seconds into it

The ending, for an open ended game, really took me by surprise. I wasn't expecting that in the least, and I don't even know how to feel lol. The game was great, story was pretty damn awesome. By the way, when you think the game is over in terms of story line, GO TO BLACKWATER, trust me, game isn't over story wise until you see the credits roll

It's going to feel a little different now as I'm playing to finish up the rest of the side quests and gang hideouts.

Anybody else beat it yet?
