Ayy, nice! I got a base 14" M1 Pro myself and it’s a blast, especially thanks to that display. The refresh rate, brightness and colors are amazing. If you’d like to stay with a single computer, I’d totally recommend upgrading to it as the performance makes a lot more games playable.
Check out the Create mod in Minecraft if you like Factorio, you will love it. It’s basically Factorio but in Minecraft. Oh and Hades should run well on your MBA as well, I’d recommend you try it if you haven’t already!
