RE: What is darkstone
Sure, no problem.
I even have quests that multiple teams can play or whatever, or two sides, like one play good and the other evil and they have to compete. It even adds a bit of nonlinearity for single-player. To date, I think I'm the only quest editor that has done that, and I'm steadily working on it until I can get the revised version up. It's at 2.10 when it comes out again.
