Being Kree meant Nebula had certain genetic advantages, but being a cyborg meant she had even more on her side in terms of enhancements to perception, reflexes, and natural ability. A game like this was right up her alley in terms of ways to use those abilities. Thor did his best though, finally able to dial it back enough to actually play the game instead of just spinning his little stick-men all the way round every time he tried to flick the handle. He got a lucky shot, right past Nebula's... goalie? Was that the word? The ball went in the hole and the score counter ticked up. That was what mattered most.
"Thank you." He said with a smile when Nebula actually complimented him. "You're picking this up quickly as well. Again." He repeated the last word from her, then they started the third stage and had a nice little back-and-forth for a bit. In the end, Nebula got another one past Thor, bouncing it off of a wall and then into one of her characters.
