Stardew Valley’s success had more to do with smart marketing than anything. The game has the exact same formula as Story of Seasons and Rune Factory, which are very corporate-run series, just not at AAA scale. The difference was Eric Barone cultivating word-of-mouth marketing via influencers and online communities to reintroduce the genre to the Western market (along with lucking into capitalizing on what was then a more nascent pixel art indie gaming trend).

Undertale’s a good example, though (I’ll still note this particular example is a huge spoiler). I did the thing and it was a very fresh idea, and one of the best hooks I’ve seen in a video game. Thing is though, I doubt even 10% took that route to see it. That’s something the game has in common with Baldur’s Gate 3, which is full of those low-percentage moments. AAA devs don’t like investing a lot of resources into things most people aren’t going to see.

Or buying a lot of MTX in few games.

I know gaming enthusiasts don’t want to hear it, but a huge chunk of the market is people attached to one or two live service games.
