Fallout 1 is great, one of my favorite games, but you do have to be ready to accept the 1990s presentation and tech. It can also be very difficult (but never impossible) if you don’t know what you’re doing.
Vanilla playthrough character: Speech, lockpick, small guns. Minimum charisma, high intelligence and agility. Gifted trait.
If you ever meet the used car salesman, don’t leave until you find the Red Ryder BB gun. Not the normal BB gun. Red Ryder.
