I really miss the pre-internet days when I’d buy a game, never worrying that the company’s server would be offline, that they’d sunset support rendering the game unplayable, harvest my data, or engineer the game to coerce me into buying extras.
You could try substituting bread flour. It has more protein than all-purpose flour, therefore develops gluten faster with less working and resting. But I make hand-pulled noodles from all-purpose flour with 15 minutes of working. I can tell when the dough is ready by how it stretches when I twist it.
Don’t use cake flour. It’s a lower protein flour that is designed to not make much gluten.
Have a machine dedicated to gaming, no Internet access, with a swappable SSD. Make a clean OS install. Clone it to an external backup drive, then disconnect the backup. Install and play. If you want to play another game, format the drive, clone the OS from the external backup, install and play. If you want to play multiple games, have them on different SSD drives.
It’s hardware sandboxing.
I don’t know how much your electric rate is, but a router or server that sucks down a hundred watts 24 hours a day may be a concern. An arcade machine would be my choice.
