I 2nd this I beat the game last night and I'm very impressed with what Obsidian did with the game and the endings. I got it done in 35 hours and I only had it freeze on me twice.
Mine was about 45 hours, not doing everything intentionally so I can still experience new things the second, third and forth times through.
With a game THIS complex there will always be bugs. Some people are still not even able to play and I feel for them. Im just glad I was able to sort all my performance and bug issues out my self (thanx to the community)
********POSSIBLE ENDING SPOILERS********
Things i didnt do that i DIDN'T KNOW i could was:
-help the mutants and nightkin
-stop the fiends from vault 3
Things i should have done was:
-install the sheriff not the robot (i think)
-not stage a coup on the BOS and not blow them up
-Do Rauls quest
-help the followers more at Freeside (?maybe the Doc there?)
-keep papa kahn in power to see what happens
