Longer Asnwer: Binary true. All of the above. Pick one.
The choices you listed are all in the area of your preference. If you had said sub or go AI then I could say the preference is definitely sub. Or quitting without telling anyone and only apologize when you get back, I could say that doesnt go over well.
I guess if I had to pick just one, it would be sub.
Yes, I noticed you mentioned you didn't want anyone going AI.
OK, so we'll see who (if anyone) has been eliminated by then, that would make a natural sub, since they'll know what's happening in the game at that point.
