Fair, but this really only matters if it's the same character(s) recurring every time.
I think however that it's fun because of the wild variety of entries you can get.
Like in the greed island one we had Rej as Elon Musk and myself as Todd Howard, fighting against the hamster from overwatch, Johnny Soreballs (literally we were so afraid of odd that game and we facepalmed so hard once we saw he was literally a vanilla townie)
So fun having those absurd interactions
