This misconception with DRM making it unplayable on steam deck I think stems from 3rd party anti-cheat software flagging Linux players. Denuvo “works” fine on steam deck and Linux as a whole, same goes for anti-cheats. Developers always have the option to tune the anti-cheats to allow Linux players, but only some of them do.
They rat-fucked Kojima towards the end of development of MGS5 and then raped the corpse of the FOX engine with that shitty MGS zombies game. When that didn’t work they decided to take a break from making video games and transitioned most of their development resources into making gambling house games for casinos. All their IPs went away for a while but I think they’re trying to get back into making games more recently.
What’re you even talking about??? Epic takes a revenue share of every game made with unreal engine, plus Fortnite runs exclusively on mommy’s credit card and is still insanely huge. Even if the epic games store doesn’t take as big a cut of every sale, they’re held by daddy Tencent who’ll probably kick em some lunch money if they’re actually desperate.
