Morrowind! Epic characters (Gentleman Jim Stacey, Eno Hlaalu, Orvan Dren, the guy in Tel Fyr, Telvanni wizards, Duke Vedam Dren, Lord Vivec, and so on, and so on...), long (!) guild storylines, large variety of factions (Fighters, Mages, Thieves, Temple, Morag Tong, noble Houses, Legion etc, etc), decent main story, for that time beautiful elaborate surroundings and a very appealing variation in these surroundings (from the Ascadian Isles to the Grasslands, from the northern islands of Sheogorath to the ashlands surrounding Red Mountain). Beside that the three main political houses (Hlaalu, Redoran and Telvanni) constantly competing, the option to BUILD YOUR OWN FORT / TOWN and of course Keening and Sunder (my dears!).

But the Morag Tong were the best, they would - for that matter - own the Dark Brotherhood anytime.
