Wow much interesting post / topic!
I guess i would consider myself an ex hardcore gamer, i do still play on occasion, but i played more seriously a few years ago. Nowhere near the pro-leagues though. Many evenings have been spent in the deep dungeons of world of warcraft, in diablo II / III, i used to play a LOT of counterstrike, there’s starcraft II, and the list goes on 
I still have most of these games installed on the same laptop as i keep and use my DAWS.
As far as similarities go, both types of software make me wish i could buy a better computer, i think perhaps the most prominent similarity in the games i play and messing with a DAW is the neccessity in learning and using hotkeys in order to be effective. I suppose there are other similarities to games i don’t play, like attention to detail etc… I’ll let others weigh in on that…
