I'm going through each city of the game as I decide which mods I'd like to look for. Starting with the Imperial City, I've so far noticed the lack of NPCs and the emptiness of the Arena. I'm currently using Extended Imperial City, which has been nice so far, but I was wondering what most people use to solve this issue. Also, that mod does nothing to the arena, which could at least use more spectators if nothing else.
Thanks for any input I get. I'll probably keep looking for mods as I move through different towns.
