Skyrim has a lot of NPCs that players can interact with, and a clever mod has made use of AI to give them memories and more dynamic conversations. Typically, once a NPC's dialogue options have been exhausted there is nothing more to be gained from interacting with them, and players have criticized Skyrim for its seemingly small pool of voice actors since many NPCs draw from the same pool of stock dialogue. Some Skyrim mods add new dialogue to help alleviate this issue.
