I've had FO3 on Steam for along time. Big fan of the series in general. Somewhere betwwen windows 8 and 8.1 the game became unplayable with each update. Now on Windows 10 Steams FO3 get 1-3 mins before a crash. GOGs version does not use wondows live so your stability is much closer to FO NV. Meaning other than the Xbox version this is the only other stable version. Unlike the xbox the PC version runs at a civilized 60fps and mods, mods, mods. I am so glad I can enjoy looking for my father again.
