Most single player steam games are cracked anyway. The real danger of steam is the reliance on it for most multiplayer games. Though if it were to get particularly nasty I imagine adding aftermarket multiplayer functionality would probably be in the realm of possibility. If private WoW servers are a thing, it stands to reason that the same can be done with a lot of other games.

I would also like to know this. I’d rather not start making content only to realize I picked an instance with insufficient resources or that’s just going to disappear in a couple of months.

It is incredibly obvious that CAPTCHAs are at the very least a way of exploiting distributed labor to train AI.
