Is there a penalty for quitting a Versus A.I. game where all of your teammates are A.I. controlled?
I can confirm that dropping a vs. AI game will be permanently recorded, and will count as a loss in your records.
I dropped an AI game simply because I didn't have the time to finish and was dissapointed to see that my loss (which wasn't really a loss, I was winning) was logged in my records. And it will sit there, forever taunting me.
