Have ps3 Cant buy both which is better fallout 3 or new Vegas. Which has fewer glitches. Also offtopic gonna buy morrowind goty of oblivion goty for pc too.
Personally, you'd probably be good with either game. I love them both.
Perhaps you have a preference in regards to setting? Fallout 3 is set in post-apocalyptic Washington DC and surrounding areas. As well as DLC locations in Pittsburgh, Point Lookout Maryland, an Alien Mothership, a Virtual Reality Simulation of Anchorage Alaska, and an Airforce Base outside of DC (AAFB).
New Vegas is set in post-apocalyptic Las Vegas and surrounding Mojave Desert (including Hoover Dam). With DLC locations in the Sierre Madre Casino, Zion National Park, Big Mountain Research Center, and a place called "the Divide".
Other than that, New Vegas is more up to date, with more weapons, improved gameplay mechanics, and better writing.
While Fallout 3 (in my opinion) is absolutely superb in both setting and exploration features.
