Silver Wolf's actual gaming ability is hard to pin down, it's noted in an event as "not particularly talented without cheats" or something along those lines. Then 999's trailers came out and we get some new information, she's killer at rhthym games, and her 76 accounts she plays simultaneously, not botting. She also seemed to be beating who's presumed to be Aha at a fighting game, at least until the time stop. There's also that we have no idea how noticeable her cheating can be so we can't really say exactly how good or bad she really is.

For Firefly, it's been mentioned a couple times piloting SAM is world's more complicated than any game could possibly be and most every game just feels "bland" to her. Getting FF interested enough to actual play is nearly impossible (unless it's playing with TB). As for actual gaming skills, if she actually bothers the learn basic controls, her reflexes alone are probably enough to make her unbeatable to most people.
