As much as i love the Elder Scrolls series (i've played way too much Oblivion), i find myself loving the Fallout world so much more.
New Vegas, when fully updated and with a few choice mods, becomes a truly stunning game that suits the engine so much better.
And sorry, but losing a battle twice and then finally going 'fuck it' on your next reload and whipping out your fat man is simply one of the best feelings ever. I'm a vindictive asshole, and saying 'fuck you and all your friends' is just so excellent.
So yeah. Elder Scrolls is a great series, but i find myself playing New Vegas more than Skyrim. Hell, if NV had destructible environments and some more content i'd pretty much play nothing else.
