Some chap invested a lot of time into making the Skyrim experience nicer. I recommend you check out CHIM :)

Quite a lovely project, but you will have to spend some time to set things up. For example, if you have a good GPU available, you can set up TTS for NPCs, STT for yourself, and then a decent LLM to handle the world interactions. The NPCs then can listen to you talk, follow you, do stuff you tell them (like attack someone, or pick something off the floor), etc. It’s something quite revolutionary, if you can spend the time to get it to work. If you’re looking for some LLM provider on the cheap, nano-gpt has an 8 dollar per month tier that gives you “fair-use unlimited” access to open source models. Worth a shot!
