And just to add another layer to this topic, (just because I didn't wanna start a new topic that's so similar to this one) what makes for good horror these days? Like what is it that stands out as unique against the rest? So much has been done at this point.
Is it jump scares? Strange imagery? The mere possibility of a threat without there ever actually being a threat? I've noticed what I call "minimalist horror" seems to get a lot of attention lately.
Well the old SH games set the bar for psychological and plain horror combined and still hold up today story and atmospherewise but no longer gameplaywise. I love these games and one of them is in my top 5 for sure.
But a 'good' horror these days is associated with how many Youtubers/ Tvitch streamers play your game, as long as you managed to make them scream (even fake screams count) then you're good because that's t least enough to get a percent of their viewers trying your game. I mean why bother building a world and writing an associated lore with it if you're only going to get 100 players at most.
Go for the cheap scares route. You only need to work on graphics and searching for the best open source scream audio.
