Morrowind remains the greatest TES ever made. The most unique world, atmosphere and biggest immersion and role-play value for a singleplayer. There are just so many possibilities even if you passed the game twice already. Bugs and exploits were present but nothing that tempted me to break the game immediately like smithing in Skyrim...
I still cannot forgive Bethesda that they made Morrowind get Red Mountain'd per lore. I nerevar asked for this.
