Uh... I got FO1, FO2, Tactics, including the manuals and booklets and what not...
I went for GOG for 1 and 2 as well, since my old disc edition wasn't working anymore(scratched to hell). It has PDFs of both manuals and the Fallout Bible, which is nice to have, since I'd probably lose a paper manual.
I had NO intention of getting Tactics, I just hate the game. No offense to anyone that likes it, but most of the game grates on me as "wrong", far moreso than Fallout 3.
GOG's DRM-free, infinite downloads with the ability to burn to back-up disc works fine for me. I don't have to play with a disc in the drive, I don't have to burn and mount an .iso, and a PDF manual is far better for my incredible inability to keep track of my physical manuals. Save some trees.
If you really wanted to add on Tactics?
$5.99. Now it's $18, less than $20, and no shipping. Plus, instant download.
