If you really want another game with Fallout 1-like gameplay, check out Atom RPG. It's currently $6 on GOG so it's probably for sale on Steam too. I got stuck on that one too when I got to a point where my melee-focused build was causing me to get blasted to bits before I could even touch my enemies in a crucial part of the game, but at least I had dozens of enjoyable hours of gameplay before I got to that part.
