Nintendo is the first thing to come to mind. The super nintendo and N64 were easily the best part of my childhood. The gamecube had some extremely good games on it despite not being able to quite stand up to the colossal library of good games on the ps2. Then came the DS, nintendo's foray into gimmicks. Some decent games on it, but anything that was heavily dependent on the touch screen and stylus felt awful to play. Then came the wii. At the beginning of its development cycle everything remotely playable was a gamecube game wherein "make literally any motion with the wiimote" replaced the B button. Over time that transitioned to "do this specific action that the wiimote won't register as well as you want it to." This also marked the first time when I felt like nintendo did a bad job with their major franchises, and it seemed more like a consistent trend than an awkward misstep. The wiiu seems like a bad concept and none of the games released or announced for it look remotely good.
