To anyone having issues running on a pi it’s likely either or both of the following item -cheap 5v power supply. Yes you can use an old phone charger but it won’t cut it for long term usage. Get a quality unit or better yet the branded pihole charger. We ended up with a Poe hat that it runs off. Sorted Ethernet and power supply.
-memory card. Buy a quality, fast card and you will be fine.
Going on 8 years with my current pi setup. One failure around 6 years in which was the memory card
GoG is generally the better alternative to steam than epic.
Steam isn’t perfect but it works and has a decent consumer oriented service. GoG is doing great with conservation and drm free options but their launcher isn’t amazing. Pair either with Heroic games launcher or similar for a great experience on almost any OS
