If Linux based handhelds keep getting more popular for gaming, to the point where they represent 5 or 10% or even more of the PC gaming market share, I feel like incompatible anticheats could spell the death of some games when competitors come up that are compatible with the platform.
I don’t expect league of legends to die as a result of this and only this but surely it’s a possibility. From the time I used to play league, I never really seemed to encounter any cheaters (or at least not enough to notice it) over hundreds of hours played. I really don’t see the value proposition to adding it, where I can understand it more in a FPS/TPS.
Of course it’s just as likely, if not more so, that the deck and similar platforms are just a phase, or that a windows based handheld takes the market by storm.
