...the tough get confused and go do something else for a while.
I've officially put about 68 hours into Fallout: New Vegas, by my Steam account, but about 55 hours into the game according to my saves, because I've done a bit of backtracking and reloading. Some of that's been due to bugs -- a quest not proceeding as it should (I still can't make the one at the Camp McCarran tower work properly) -- but a lot of it's been down to me being indecisive.
From what I can tell, there are a total of four different quest arcs you can choose from, to reach the end of the game and complete the story. I know I have no interest in helping the Legion, ultimately, but otherwise I'm still undecided about what the best or worst outcome for New Vegas may be.
And on the one hand I like that the game isn't as clear-cut as Fallout 3 was (Brotherhood good; Enclave bad), and I enjoy that there are a number of different major and minor factions at play. But on the other hand, I have this burning need to follow all possible roads as far as I can. I think, for the three or four end-game series that have stages 1 - 7, I can get up to about #3 or #4 on all of them before I have to pick one path and stick with it. So that's what I'm going to do. But I can tell it's going to get very tricky...
(In the meantime, folks who like me include the NCR, the Brotherhood, the Strip, the Followers, and a number of towns around the Mojave Wasteland; folks who really can't stand me are mainly just the Legion but I have a safe passage token for them. The other baddies are not pleased with me but only one of them is kill-on-sight (and not the ones who Vilify me, oddly) so I've been free to explore the map. Only 8 locations left uncovered!)
