While not exactly (the same)Gwent it is related so I’m posting it here…
I recently (re)started Thronebreaker on Switch. When I initially bought it it didn’t really click and I just left it alone. I am really enjoying it now. The story and voice acting is top notch, like you’d expect from CDPR and it actually does some interesting things with the Gwent formula.
There are lots of normal battles that work roughly the same as the multiplayer Gwent but it also has puzzle battles and battles with special conditions that spice things up a bit.
Definitely give it a try if you have an Xbone as it’s part of game pass (console only).
