You'll have a blast, very reminiscent of FO1/2 some of the writing from Van Buren was also adapted for NV. Personally I think it's the best fallout after 2.

3 is a fun game but Bethesda will never be able to write RPGs like Obsidian, the company just doesn't have the same principles to do something like that

I would avoid the rest of series if I were you, it's a cash cow series for Bethesda now
