One of the biggest games right now is an indie horror game made by a solo dev,
Lethal Company was for a time top of the Steam sales charts. It's hit metrics that would be respectable for a AAA title. On one hand it's a horror co-op game with janky mechanics and opportunities for hilarity. Co-op horror is popular and this is a great platform for influencer shenanigans, but also lots of games all want to be that.
Lethal Company is also a game about being in a capitalist dystopia that destroyed not just the world, but every world and every moon. There is nothing left but scraps to scavenge for and a glimpses of what life was like before the collapse. Workers are literally disposable. That is striking a chord.
I have zero interest in playing it and get bored watching it. Janky mechanics = hilarity is not my thing. But it's a very interesting phenomenon, especially since such a big satisfaction point for players is deciding to hold back salvage from the company, even though that can mean not hitting quota.
