I saw a copy of Fallout 3 (no DLC) for 10 bucks so decided to start that.
It's a really interesting game. So much to explore.
But I'm frustrated by how clumsy the real-time combat is (VATS is cool). Compared to games like Mass Effect 2 and Uncharted, the innacurate nature of shooting combat in real time is grating. I hear it was even worse in Oblivion. I hope they fix all that in Skyrim.
I find the game a little difficult too but the exploration is great.
