Am I right with this definition?
Sleeper hit: A game that did not get the "essential" treatment before release, but that ended up being perceived as such by critics and gamers in general.
Splatoon is definitively a "hit". But I have the impression that the game got way too much attention before releasing to be considered "sleeper".
With that being said, the best candidate for this category IMO is Rocket League. It took every non-beta tester by surprise.
