Along with @Null Signal Games for Android: Netrunner, I discovered today the existence of @Emerald Legacy which is also a community-driven project to maintain a #LivingCardGame (LCG) after its original commercial publisher ended support for it, this time for Legend of the Five Rings.
Having been completely absorbed by Magic: The Gathering in my high school years, I've never looked too much into either games when they were still commercially supported but I'm still glad that they are living on thanks to the work of volunteers,
Cheers!
