Also, when playing Fallout 1, I often enjoyed just staring at the world map, listening to the music, exploring the wastes and getting random encounters. Which were far more interesting than the general "Do you wish to encounter (insert group 1) fighting (insert group two) [and slaughter everything]?" In Fallout 1 we could encounter Brotherhood patrols, and demand them to take us to Lost Hills, people attacked by raiders, than kill the raiders and *actually* get rewarded ("For your help we award you these 382 cap", brings a tear to my eye), Patrick the Celt, caravaneers with names, fishermen, Hub patrols, old battlezones, we could go on regular, unbugged caravans to different cities, explore ruins of old (Vault 15, Vault 12, WestTech Research Facility, Barstow, LA Boneyard and it's random encounters), get Tarot readings, fight/sneak ever-respawning Deathclaws, become a member of the Brotherhood of Steel (damn, so little quests...), impersonate a Child of Cathedral in Mariposa and the demonstration Vault, get 'healing' from Dr Wu, expose the underground cannibal ring, work for the mafia, and I mean *truly* work (Daren Hightower's assasination, Jain's...), become a member of the Thieves' Circle, get Dogmeat, Ian, Tycho, Katja (such beautiful NPCs... yes Ian, you too. Now, stop shooting me and MOVE from the corridor!), equip opressed Adytowners with guns for their revolt (yes, I took the time and planted weapons on them, after consulting the FRM viewer), observe the Boneyard from the top of Cathedral's tower, learn about the Holy Flame and listen to Dane's ravings, talk and interact with Zax, feel the thrill when entering Glow's fifth level and terror, when fighting robots armed with only a Glock 86 and your comrades, help a farmer reclaim his home from the raiders, encounter Set, feel the depressive and crumbling atmosphere of the Necropolis, learn of Harold's history, explore the horrifying underground of the Cathedral, talk to and comprehend the Master's plan, explore the possibilities at Mariposa, finding about the Super Mutant / human romance sub plot, see CoC technicians commit suicide, eavesdrop on Van Hagen and the Lieutenant, be interrogated by the lieutenant, fool Super Mutants, acquire the help of Brotherhood's Paladins in storming the military base, wander the wastes, read detailed and immersive item descriptions, read the holodisks, with background, cohesive history...
That is Fallout. Fallout 1 is immersion and fun, I truly FELT that I was there. I felt the dusty pavement beneath my boots. I felt the fear when I was pinned to a wall by the Deathclaw while emptying my shotgun into his eyes, supported by Dogmeat biting away at him. I felt the primal instinct of satisfaction when slaughtering raiders in my T-51b and a Plasma Rifle. I felt the cramped, dead atmosphere of the Glow, as I was exploring the burnt out base. I felt satisfaction, when I ended Master's vision. I felt the disappointment and anger, as I blew away at the Overseer, ending his life and reign.
I can write like that all day... but one thing will sum it up.
Fallout is an experience. Fallout 2 is (just) a game.
