I think it would be awesome. I have friends who want to play it, but aren't interested in eso, not to mention paying for High isle.
So I suspect it doesn't make sense for ZOS to even consider making it a standalone game until it stops motivating people to buy High isle. After that? Perhaps.
Only after Orgnum desk completely removed, of patron re-done to follow the very idea of desk building.
Right now it is ruining the game. In it's current state - no. Just because of the said Orgnum patron spam.
Yes! as a matter of fact, it should BE a stand-alone game only. When I play ESO, I am pulling between 260 and 390 watts from the wall. A card game such as this can be played on a smartphone or tablet for 15 watts or less!! No way I am going to run a full-blown gaming PC to play a card game in a game..LOL. That IMHO is not good common sense and wasteful. Personally, this may be a great feature to be made accessible but NOT here.
