OUYA just continued to piss me off by not even bothering to make sure their experience was good and brushing it off by doubling down on marketing on how cool they were. They slapped android on a Tegra and called it "good." At no point did they try to unify the controller api, yet they claimed to support multiple brands/types of controller. It was on the dev to map each one when they can't even predict every brand. I had controllers work in one game but not the next! That's unforgivable. Either handle an SDL2_Gamepad style mapping at the ENV/system level or just say you only support OUYA controllers.
When they were getting complaints about overscan (ugh, why do we still need to deal with this (aside: holy crap iPhone X, not you too!)), they elected to just force-scale the UI down by an inch (memories of PS2) and again tell the devs to just deal with overscan themselves on a game-by-game basis. A good solution would have been to make overscan a system setting that the games could query ("oh, btw, your display area is actually 1900x1000, offset by 9px left, 25px down").
This pattern of "slap a fix on it, and then plug your ears and yell 'LALALA'" was what killed it, and probably all other attempts at an indie console for a while. Hopefully the world has forgotten the OUYA enough that this has a chance.
I mean OUYA didn't even have a useful recovery partition COME ON.
