Originally needed them for modded Minecraft. I ran out of keys on my keyboard for all the keybindings that mods wanted.
Also tried using them in ffxiv, at least for the short period of time that I played it (fun game but I don’t have the time sadly).
The price of one game is not a problem for the price of another game. Make better games, or learn to market them better. Silksong’s hype is nothing short of a crazy marketing success, and its price is indicative of a dev team that wants people to actually play and enjoy their game.
Also, I think it’s been made very clear that people would have been willing to spend more for it. Make a great game, and you’ll likely receive the same reception. And sure, charge $30 instead, and people will buy it if your game is good.
