Keeping things simple.
I would be cautious too if I were a sub owner and guiding people to an alternative honestly. Lemmy and Kbin both are relatively unstable right now, even if they are pretty good. Waiting a little to see which instances are more stable and likely to last is a good move before planting people somewhere and making an official replacement sub.
Elden Ring is such an easy choice. Just a fantastic open world that encourages exploration and discovery. I think you should give it a second shot OP.
