I managed to run The Sims 4 on Linux after over 6 hours
At this point, making something that doesn't work using Wine or Proton is actually kind of an achievement, so congrats EA, you managed to fuck up both Origin and EA app. The actual game runs flawlessly, it's the launchers that are all kinds of broken.
Wife likes modding Sims and already bought some expansions before we moved her to Linux. They actually still add some free content sometimes, so we keep the wifey happy, and hope to almighty Gaben that EA doesn't fuck things up too bad. Good news is that she knows that when things go wrong, it's 100% on EA
