For Linux, you can run your own windows program in any linux distro because of Valve (from Steam): they have a compability layer called Proton that runs any windows program directly on it - including ALL games!

The best office alternative is not libreoffice, but one called OnlyOffice that's basically a open source copy of windows 2016...it's awesome.

For google drive, you can use RClone or KIO Gdrive. RClone is the best as it syncs as a normal folder. Anything you need, let us know.
