If I tried to answer this question, I’d be here for hours and…
Billy and Teddy had at least one long term MMO experience. Billy’s is probably still ongoing. Both would like large-scale RPGs, Billy to the degree of having written fanfic about his Player Character in Dragon Age.
America would answer that she doesn’t play any games, but if prompted with a “what about XYZ?” she’d go “Oh yeah. That doesn’t count!”
Noh-Varr can rant about Robotron like he rants about Be My Baby, though being a Space Invader he finds certain aspects of classic gaming problematic.
Prodigy likes games that feature a lot of terrain and may even need you to read the PDF manual. He’s probably programmed his own.
Kate… well, there’s two ways of looking at Kate, which require subtly different readings of her, and what she’d play. The one I prefer has her playing a bunch of stuff on her mobile, and multiplayer stuff when she’s over at Billy’s. She’s the sort to add sarcastic comments any time a videogame gets the archery animation wrong.
Loki is always playing a game.
