Why bother? You can get an sbc PC with a decent agpu, throw SteamOS on it and have the little PC console of your dreams. There’s a few good 6600U ones online. $300-$400. You’d dwarf the library of an arm console limited to Android, even with emulation.
I think they really came into their own, commercially and artistically. The whole game has a clear, crisp gameplay, and a new sheen of consummate professionalism that really gives the style a big boost. It’s been compared to Valve, but I think Riot has a far more bitter, cynical sense of humor.
