I will only comment on one part of that. I only thought inspiration was awarded if Doubles were not rolled.
Also, I thought GG was handled differently in a 2x2 game.
The rules are clear on this. The player rolls for Tension, if the Final result is Doubles then players lose GG. THEN the rolling player uses the Tension dice to assign Inspiration either to his characters or to gain Kama.
It is not one or the other; That would be unfair to the player rolling the dice.
