Honestly? Use the wiki to look up quest givers, but don’t use a walkthrough for the quests themselves. Fallout 1 is great and the cities are fun to explore, but the (generous, I should add) time limit stresses me out and I like to be constantly progressing. Instead of wandering around looking for quests, I just find out how to get them in the first place, and complete them as best I can with no other help.
