Pathfinder's compatibility is based on 3.5e, so DnD 3.5e homebrew stuff is likely to work with Pathfinder. 5e stuff probably will not.
Old Windows games are more likely to run successfully on Linux than Windows.
New Windows games supposedly run faster in modern Linux than modern Windows. I can't verify it, lacking a modern Windows installation, but tomshardware.com said it was true.
Yeah fair there's loads of third party content for DnD. There is also for Pathfinder but not quite as much.
That being said, I've found the core system gives you more customization so there is not a constant need for outside content to keep the system interesting.
Yeah, you can make anything from classic knights, to mystery cultists, to fucking magical girls natively in 1e. You don't need a billion dollars of 3rd party supplements to make whatever you want, it's just there in Pathfinder.
Hilariously, getting better for both of them. Pathfinder has a lot of third party developers already, and gained some after the big D&D debacle when Wizards tried to update the OGL and kill third-party. Linux is still slow going, especially on the gaming side, but a number of FOSS companies and Valve have done a lot of work to legitimize Linux as a personal computing platform.
"-but you can apparently get a few toxic elitists"
APPARENTLY?!? You guys must be in much better behaved circles on the internet than me to word it like that.
Honestly, breaking away from D&D has been amazing. We've learned so many cool new systems and honestly, it's been a lot of fun.
There's a lot of smaller systems out there that are amazing, don't just try pf2e!
Getting away from d20 systems after a long Pathfinder campaign with my group has been great. All kinds of systems out there making you roll d6s or d10s, spend hp to cast spells, and build characters collaboratively.
I'm an active Linux user and I can say it is a few, they're just so fucking annoying. They seem to respond to absolutely everything with a ten foot stick up their ass.
The rest of us don't care and don't really talk about Linux unless you need help or are genuinely curious. Basically you almost never see a comment from the rest of us because most of us are probably introverts.
I'm definitely a Pathfinder evangelist, but it isn't my favorite genre or the one I'd most highly recommend for a newbie (unless you are just really into the setting). I recommend trying Chronicles of Darkness out if you want a game that is actually both isimple at it's core and easy to add content to, it's what i recommend newbies every time.
The base systems are easy to grasp and mostly applies to every part of the game, the point buy system makes it simpler to follow character advancement (no set growth so you only need to remember what's on your character sheet), and the setting is incredibly easy to grasp (well, the parts you are supposed to know, it's just slightly worse earth with vampires and werewolves and mages oh my).
