Definitely Fallout 3. I loved the weapons, characters, towns, everything. But one thing that stood out for me was the location. I mean, who doesn't love wandering around a post-apocalyptic Washington D.C.?
New Vegas was good, but I felt that it was WAY to glitchy.
your right it was really glitchy the reason it's my favorite is because it was my first (i know i suck .) but i loved fallout 3 the dlc's were great like operation anchorage
fallout 3 all the way, it was so awesome it had such a good world with the characters and the towns and my favorite part was the sound track, oh it was so amazing.
Fallout 3 for the win. I've played Fallout and Fallout 2 but never completed and New Vegas it's kinda boring. Fallout 3 with the expasion packs it's EPIC!
