I used to play on the regular world (RSC Preservation, non-bot). There's not enough people. And probably won't be hardly anyone there when I'm old enough to be in a nursing home.

I could join the bot worlds, but I'm fairly certain that they don't talk much or behave like a normal player in general (stumble through quests, make friends, trade with other random players, etc.). They probably just grind skills in some optimal way.
