Sounds like you’ve already answered your own question.
It might die. If it does, it’s not a super big deal. You have backups. You don’t like creating unnecessary e-waste.
As gets have said, crystal disk info can help detect any existing problems, but it can’t predict the future if something happens suddenly. So it can be a good indicator, but don’t assume it’s 100%.
I loved it until I didn’t.
Don’t remember how far I got, maybe 2/3 of the biomes, then I burned out and got bored. That was a while back, and flattening the land was really glitchy. I’d have an area perfectly flattened and ready to commence building, save it all down, come back next day, and it’d all gone to shit again. I got sick of trying. It became more of a grind just to get back to my last save point than I wanted, and gave up on it.
Did it ever get a full release?
