I switched from the Italian layout to ANSI for the same reason, bought a Keychron and wanted more choice in keycaps.
Honestly it wasn’t as difficult as I thought, it was like learning how to drive a different car after using the same one for years: some buttons are in different places but the thing itself works the same way.
I also like to collect old video games but I don’t think I ever stopped to think about why I do it. I just like having them, even just seeing them all lined up on a shelf, knowing that I have pieces of gaming history in my room just makes me happy. There doesn’t need to be a real reason, sometimes we do things just because we feel like doing them. Do things because you feel like doing them and not because you have to justify them to other people.
