Seems perfectly reasonable to retract the award when they admit to breaking the rules.

I think they need to define the rule better though for future years.

"Games developed using generative AI are strictly ineligible for nomination"

The strictest interpretation of this would mean that any single developer using chatgpt to ask how a C++ function works would make the game ineligible.

Clearly that's not the spirit of the rule (since I think that basically exclude all games at this pointso) so it should be better defined.
