Morrowind is one of my all time fav computer RPG's ever.
I have all 3 sets of the game, (game and 2 addons) and have beat the entire thing 3 times so far, and the main quest many many more.
I love just collecting stuff like a pack rat and building a house to store it in to show off.
And my opinion stands strong that morrowind DOES NOT need multiplayer, I've always hated multiplayer rpg's.
