Not able to join the Enclave during Broken Steel gave me the biggest rage.
Why the hell would you expect this? If they did implement this, then the gameplay for BS per character would be halved, which wouldn't be so fun for most people.
I was angry at the Outcasts, like most people. It mostly gave me amusemant, though. They told me to bang rocks together, so I sent a rock their way. By rock, I mean mini nuke.
Nothing really to "rage" over, since there isn't much to rage over.
I was annoyed that there wasn't any Oblivion-esque Factions. To be able to join the Enclave (only the Eden followers, or the game would be boring. We don't know what type of Enclave was in AFB though :shrug: ), Raiders (only a group, so most Raiders stay hostile) and maybe even Talon Co. would have been awesome, especially since the factions added loads of gameplay for me in Oblivion (Dark Brotherhood FTW!)
Nothing to shout over, or anything to affect me physically.
