It's difficult, because games need to be "good" mechanically or they're by definition unplayable.
Most "so bad it's good" involves either accidentally tolerable jank (Bethesda games), or bad but hilarious writing (Red Alert 3, just as an example).
However you'll never see a Manos or equivalent in vidya because the worst of the worst movies fail at even basic cinematography, and no game is worth anyone's time if it is unplayable - even to be enjoyed ironically.
