I think HD textures is a pretty reasonable baseline for 2024.
HD texture doesn't enhance roguelike deck building experience that much, since it's a very game mechanic focused genre. A properly made addictive roguelike deck building is still equally addictive even if all the cards are made with MS paint in 30 secs. I can probably play Slay the Spire all day even if all cards have no graphic, just icons and numbers. Because it is the interaction of those numbers that made those games fun.
But HD texture makes it much harder to run on a potato PC.
It seems like the gain doesn't outweigh the loss.
I have a potato PC with with 4G ram and 64 gb emmc. My space is often below 3-6gb until I delete stuffs. Balarto's system requirements is 1gb ram and 150 mb available space, actual game is less than 100 mb.
Change texture to HD we'll see the system requirement skyrocket, to a point that even potato PC like this may not run. And it doesn't even enhance the core gameplay, what's the point?
If the game works with 100 mb space without hindered experience then the lower the system requirement the better imo.
Great games dont sell poorly.
How well a game sells depends on the target audience number(market size) and market saturation(competition). Quality matters in the competition within the same genre but it is not the only variable.
Same rules applies to every type of product in the field of business really.
Sometimes innovative games don't necessarily have the biggest market size unfortunately, because it's not "mainstream".
