I’m glad you’re enjoying Fallout 2, it’s probably my all time favourite Fallout! Are you playing with the Restoration Project?
I know exactly what you mean by that early game bottleneck. FO2 can be rough in the early stages between lack of equipment and the comically unbalanced random encounters. It usually swings the other way once you can survive big encounters and sell the looted weapons after.
How far have you gotten?
From looking at the GOG store it doesn’t seem to be bundled with any patch, which is actually unusual for GOG. If you’re interested I heartily recommend Restoration Project, Updated or RPU for short. It’s a combined unofficial patch/cut content restoration that’s very vanilla friendly and tidies up a lot of stuff left unfixed in the last official patch.
Yeah those Wanamingos are scary in the early game, definitely a place to come back to later. Armour can be tough to get as it doesn’t typically drop as random loot. There are two leather armours for sale in Klamath I think if you’ve gotten a bit of money now.
