Some games are genre-defying, and so fall through the cracks of classification schemes based on how good the game is to appealing to fans of particular genres (e.g. does
Undertale appeal to fans of bullet-hell shooters?) while still being otherwise agreed-upon as "good." One of the purposes of a general, non-genre-specific "Hidden Gems" game list would be to help you discover such games.
