Since last update, 2.13 I think, it does not work well with gog games, at least was not able to install flatout and pillars of eternity, both from my gog library. Nonetheless I was able to install pillars from the epic store, using heroic. With flatout I spent a week trying to debug installation problem, clear cache, reinstall of heroic, and everything else and then simply used lutris which installed flatout at first try and let me play right away (steam deck)
I come from VyOS and really liked it, but still prefer opnsense for the GUI, constant updates and plugins. VyOS started losing appeal once they opted for subscription stable iso access (even if they did give me a free subscription for some comment contribution in their repo). Also, I have to admit, that VyOS needs a fraction of the resources needed by opnsense.
