Post here all those little fun things you encounter in the game, ie. references to older fallouts and all that. I'll start with a few

Marcus, who named the Jacobstown after his friend. Jacob was that BOS paladin, right?

One of the super mutants said "I wish Marcus could get us some miniguns or rocket launchers". Those were very common in fo2, oh the horrors.

At the G.I.blues quest, when you ask the guys if they remember something about the attackers, one says something like "Hey, i think one of them shouted "Hey lou, we got to go". There was some more of it.. Like "Tenant". I think it was "Lou Tenant"." Remember harry, from FO1? There was the lietunant Lou, and harry said "He lou tenant, he my boss. not tell him, but harry could take him on good day" when you ask about the Lietunant.

Fallout 2 music in Nipton, was quite a pleasant surprise

Then there's all those small things, ie. Nightkin, doctor's bags, geckos etc. Post yours!

When running into the merchant in westside by the name of from KLAMATH! That made me happy.
And ofcourse, the vertabird pilot who mentions the crash near Klamath aswell in F2.

One word, Tabitha.

DOH! I messed up, why did I say Matilda instead of Tabitha. I'm old, my brain is rotten.

Tabitha and her awesome DJ skills on the radio (wish the station was world wide)
The stories behind every vault in NV....always love science gone awry.
SILENCERS!
Headshotting stuff from max view range......waaaaaaay outside VATS range.

Running around the Strip in a prosttute outfit and Legion Centurion helmet killing anything that moved with my Thump Thump grenade rifle. I laughed so hard that i think i pulled a jaw muscle.

Now that i think about it, that's quite disturbing.

No-bark Noonan.

I found a Wasteland Survivor Guide next to a skeleton. I want to say it was in the Casino in Primm, but I can't remember exactly.

Much of the dialog. I just ran across some NCR guy with a busted leg in a cave and I was able to shout "Boogedy boogy boo!" at him. XD
