It's 2025 and saving in absolutely every game still sucks
There are many, many things that professional game development could take from mods: better UIs, cooler weapons, what if everyone was naked all the time. But the one that most sticks out to me—that I think almost every single game could learn from and that I am baffled they still haven't—is IStewieAI's Auto-Save Manager (ASM) for Fallout: New Vegas.
It rules. Its options are numerous and robust. In place of a ho-hum, standard autosave that updates and overwrites itself whenever you enter a new cell, ASM lets you get weird with it.
