Is Morrowind the best Elder Scrolls game? 10 years later fans still passionately argue its case. But what with being so bloody old and all that, why would anyone bother playing it now?
Because of mods; because of Morrowind Overhaul, a compilation of the best mods that completely transform Morrowind graphically, audibly and beyond.
Another big plus is that compiler Ornitocopter's created a "noob-proof" installer to apply all of the mods to Morrowind. Try doing them one by one and you'll see what a boon this is.
