I play stock because: I don't want to mess around with waiting for mods to update. I don't want to waste my time untangling any additional bugs or mod conflicts. I don't want to become reliant on something that might be discontinued. I like to help newbies and sometimes make tutorials, and the base game is common ground for us all to be talking about the same experiences. But it doesn't bother me if others play with mods, though, and I actually have tried and liked a few mods here and there, but have found none of them to be necessary for my enjoyment of the game.
