This cannot be understated.
When it came to bad games-especially shovelware-the Wii was the king-at least up until recently, and counting only consoles released in the last twenty years. The PS2, and DS were close seconds, but nothing could really beat the sheer amount of garbage that was pumped out for the Wii.
People act like the gaming industry has never been this bad before when that's not even remotely true. The only difference now is that the things making it bad are not the same things that were doing so back then.
