F1. The glow obviously! There was no other quest i REALLY liked since i prefered just to enjoy the game.
F2. Freeing Vic i guess..? Taking out all the raiders early on with Vick wielding a shotgun sulik with a combat knife and myself with a 1mm pistol/magnum
Or the raiders outside new reno. Was kinda hard but so rewarding
Saving killian then taking out gizmo in fallout 1, first time i saw fallout i was like 5 and my brother was killing gizmo, always thought it was a fun quest.
From FO1: The Junktown quest of either taking down Gizmo or helpin the Sheriff
From FO2: Both the Prizefighter mini quest and becoming a Made man for the Bishop's (and banging Mrs. Bishop)
"there are two kinds of people in this world those with loaded guns and those who dig"
Plenty Fallout 2 quest I can remember. The game is just chockful of goodness.
The Den got that drunkard falling asleep on me. Then later on in Modoc someone tell me about a missing farmer, Karl IIRC. Witness the fake ghosts then Return to The Den to check.
