I may have to but I heard it was very un-polished NPC wise and I don't wanna download something unless it feels finished.
Map 1 has fully realized NPCs with quests and everything. Map 2 has NPCs populating the cities also, but no quests yet.
Although still technically a Beta, the released maps are worth installing.
Other big city mods:
Havish
Wizards' Islands
(those two both conflict with TR though)
