I know that I personally go into competitive games with a different mindset than the mindset I have when roleplaying.
If they went into it trying to roleplay emotions should be expected. Reporting that turmoil in the report is just accurate reporting.
Both my gatekeepers from this game went in with the intent to win. Granted, I did lose these games, so you might have a point, but I'm not sure it makes as large a different as you think it does.
AI Box Experiment Update #3
Tuxedage (AI) vs Alexei (GK) - Gatekeeper Victory
Tuxedage (AI) vs Anonymous (GK) - Gatekeeper Victory
I have won a second game of AI box against a gatekeeper who wished to remain Anonymous.
This puts my AI Box Experiment record at 3 wins and 3 losses.
