MacBook Air 2018 to upgrade to gaming PC?

I recently got a MacBook Air 2018. I also wanted to play games like Fortnite, Hello Neighbor, which need very high graphics and stuff. That's why I wanted to ask how to upgrade the MacBook.

Yes, you can connect a mouse via USB. So with adapter of course.

With the Air, you can't upgrade anything and play even fewer games.

A mouse certainly brings 100fps more

Clear. Intended for Tetris. You can't play more xd anyway

Not at all.

But look at the program https://shadow.tech/dede This could possibly work.

The laptop itself can't be upgraded, everything is firmly installed.

But you can buy an eGPU with Thunderbolt 3 which costs 400 euro and upwards.
