That’s all very reasonable. I certainly encourage caution.

I’ve never really voluntarily used Adobe products, nor the EA store, but I can tell you Linux support for gaming has come a long way, even for “Windows only” games. If you’re unsure about a particular one, a great place to start is protondb.com. I don’t know if they work with EA, but I’ve also heard good things about Lutris and Bubbles.

As you said, there are good alternatives, including Open or LibreOffice. You might benefit from reviewing alternativeto.net, which isn’t specifically Linux focused but has a good chance of giving you options. For example:

alternativeto.net/software/adobe-lightroom/

Good luck with your experimentation!
