I tried Regicide because of this post, really liked it.

Our few victories were always obtained by taking risks and was never easy. The mechanics are a bit overwhelming at first, but after a couple of matches the effects are easy to remember. We still haven’t found some general strategies beyond “diamonds are really useful, don’t waste them”.

A game ended after we had J♦ as the last jack and Q♦ right after it, we simply didn’t have enough cards to deal with them one after the other.

It is not different from how the previous shared libraries worked. I guess it’s there to stop cheaters from buying a single copy of the game and sharing it with throwaway accounts.
