Sorry if I didn't understand you, but, Do you already knows what TR adds? Not vanilla models or textures, but the continental part of Morrowind province, that wasn't included in the original game, with new quests, dungeons or npcs in the new lands added (at least in the Northeastern corner, the most 'complete'), to visit these new lands, take a boat or swim/fly from East Coast (specially in East coast ports becaused they can direct you to the part of the new lands with actual content, the others ports lead you to big portions of land very WIP without content).
