Honestly... I don't care that much about having a Slovak community personally, but in case I have something worthwhile to contribute... I'll see what I can do.
When I need to run terminal, it's because I'm following a specific guide to fix or setup something. It's not much different than following a similar guide for Windows, except there might be a bit more copy+paste going on on Linux.
The omnipresent mentions of terminal also delayed my switch and it was completely unnecessary.
No need to wait for SteamOS. It still needs the compatibility layer, as it is Linux. There is bothing too special about it as far as I know.
I'm a layman in terms of Linux but really... except some multiplayer titles, there really isn't much to be concerned about using Linux. At least not from my experience.
What helped me is having no expectations and not looking at it as a Stargate show. It is kinda good that way. Come season 2, Stargate vibes start to shine through, especially in the second half. It really got cancelled just as it got really good.
Best thing about these ultra specific rules is that there had to be someone who did it before the rule was in place.
