Been seriously thinking of switching to linux for my desktop. I mostly use it for games. Today I was looking at mods for Mass Effect, and the mod manager says in all caps - LINUX IS NOT SUPPORTED :(
There's probably going to be a lot of that sort of annoyance for years.
You might still try using Proton or Lutris to run it. It may be a pain to get working, but hopefully someone out there has a guide for the mod manager you're using.
Nah. What hes saying its that they are not supported natively. The game is Gold on protondb, so its playable on Linux. Just use Wine to run your mods. Simple
