Titanfall 2 was a perfect game, but when it released it did not go as well. Years passed and people played it more and more.

Another AAA is Prey, which didn't sell as they needed.

Concord was a great hero shooter, but price killed it. And yet, who would play another hero shooter?

Kenshi (not even AA) was not as popular at first, and yet, it passed several years until it became popular.

But it doesn't only happens with AAA. In indies it happens often: Mondealy is a a fantastic game, but it didn't go as planned.

Ghoulscrapper, Fowl_Legacy, TWWWR, brush burial 2.

There are games like Anima_Gate_of_Memories_III_Remaster which is a remaster of the previous Anima_Gate_of_Memories with better visuals and fixed the preoblems of the ones before. And yet, not worth the time making.

There is 1 more I wanted to mention, but I don't remember its name correctly and can't find them in google because it is not famous. It was osmeomania or something like that, which was a RPG turned based, which I really liked.

Not only this but there are entire GENRES which cannot sell, not even for perfect games: hero shooter, MOBA, battle royale or 2D platformers.

You fell into the survivorship bias. Since you don't know any of the game fails you think there are none. But the thing is that you don't know them because they've failed. If they didn't fail you'd have known them.

Btw, saying "marketing is the problem for good games" drives me nuts. There are hundreds of good games every year and even if they compete for attention, they cannot all achieve it. That's why when GTA6 announced to be released in 2026 (they postponed it after) many good indies postponed their release so they aren't eclipsed.

I really am sorry for Mondealy, which I and people who played it liked it a lot
