Some of these are just things I like but could live without if you paid me enough, lol.
librewolf (if you're wondering, I de-harden it, lol, plus I add Firefox UI Fix - Photon Style, because Proton is ugly, and I also use compact mode)

vmware-workstation-noxsave (a custom package I made)
virtualbox (along with the dkms package, lol)
gzdoom
lzdoom (occasionally)

duckstation
slade3
