Hello,
Thank you for taking the time to read this.
I’d like to propose an addition to our selection of games: Yugioh.
There are quite a variety of projects that can facilitate relatively simple implementation of this game (that is, relatively when compared to an entire engine…). I don’t really know how much time wrapping such a project would take.
Here is the link to edopro, a newer engine for this.

Regarding copyright: Konami could potentially strike qc or any of these projects, but they have been around for many many years without issues.

You'll find my emphatic approval on anything Yugioh,#seto_kaiba.
