Also, is it even true to any extent that the way you play a fighting game shows your true personality 🤔
Bit late on the response, but in some ways there's an indication, and in most others no. Some people get a lot more angry at video games than at actual people, or vice versa. What you can draw out is how people respect other players, but even that's kind of iffy.
I've seen the same ideas about how you play chess (or variants), but playstyle and personality don't match. It might matter a bit for newbies, but once you learn the game enough you'll figure out what works best for you. And unless that game and reality are exactly the same, there are going to be significant differences.
