Well, almost (49/51%).
Needless to say, the steam deck has definitely found its place playing Monster Hunter, Graveyard Keeper, and sometimes even Guild Wars 2 and factorio.
It does run Deep Rock Galactic and Vermintide 2 too, but I feel those are better played on the rig.
If there was a Pokemon game on PC, I would assume that’s what 100% of your time was spent playing.
