ReynardFox: GOG's selection process includes the rejection of genuine classics like Dragon's Lair and Mushihimesama, the curation here is a joke.
Exceed20XX: But wait a minute, seriously? Dragon's Lair? THE FMV game that's conquered many a platform? That game was denied? Was there a reason given for that? Dragon's Lair really isn't niche so that can't be the excuse.
Dragon's Lair is a great cartoon film, but it's not a game. There is barely any interaction between the player and the film.
The entirety of Dragon's Lair "gameplay" (it's not actually gameplay) consists of pressing the one exact key that the developers want you to press, during the one exact second when they want you to press it.
If you press no key, or if you press the wrong key, or if your timing is off by more than a second (maybe less), then the film diverts off its normal course and shows the main character die. If you press the correct key, the film continues along its normal course.
And there is no way to know what key to press, or when, other than by trial and error (or looking up a walkthrough). So basically Dragon's Lair is a film/memorization simulator, based on forced trial & error, masquerading as a game.
If non-games like Dragon's Lair did not fail GOG curation,
then GOG curation would be useless.
ReynardFox: Space Ace were both rejected.
Space Ace is not a game either. It's also a film/memorization simulator with no gameplay in it, exactly like Dragon's Lair.
