yeah, it is mods that make elder scrolls playable for years on end - from entire game overhauls, to new levelling systems and even massive new landmass projects
This sentence, right here, makes me think that Skyrim should automatically lose game of the year. Ewww.. Ewww... a game shouldn't RELY upon expanded content to be an enjoyable experience years from now. I've gone back and played Final Fantasy Tactics plenty of times without improvements. The FFT 1.3 patch for the game insanely improved the game, making every class viable, re-balancing broken characters and skill combinations, and revamping the end-game content to the point where it was a truly a challenge for dedicated players, but I never felt that without the patch, I couldn't have enjoyed the game.
