thanks for voting.

I voted Oblivion for "Which needs the most mod work." I was having to add mods to get rid of minor annoyances before I had played Oblivion more than two days.
I voted Morrowind for "Which requires the least mod work." But nearly ties with Skyrim in my book.
I voted Morrowind for "Which is the easier to mod." Mainly because of textures (no normal maps).
