If you're starting with Fallout 1, go in with extremely limited expectations. Fallout is a series that attracts midwits by the bushel, and the first one being an incredible mediocre and shallow game but one that ultimately still tries (even if it fails) to be an RPG is especially like catnip to them. Inside, you'll find a game with incredibly shallow combat, limited character building, dialogue that is often amateurish and with surprisingly few options for responses once you get past the initial questions, and aggressively handholding pacing through a very short game. Not to mention all the little aggravations, like how companions are incredibly underbake and use the barter system to equip them (so you'd need to buy your gear back if you want it for some reason), or how the Boneyard is rife with constantly dialogue bugs and missing progression flags (and the canon ending being impossible to get because they forgot to add the NPC for a quest you're still given)
Honestly, the first game in general would just be better adapted as a book, but not as a novel. More like that growing subgenre of stories being presented through a ficitionalized dungeon master's guide. Like a step up in presentation from the Fallout Bible
