Hi. I had been wanting to check this one out (after a few recommendations) and like you I thought it would be a good side project between SM quests. I joined under your link. My first impression is that it seems a formidable task to get my head around the basics, AND it feels a bit "too polished". For instance, when you turn over those five free starter cards there it seems too "smooth". I like how SM has the more "crisp" sound when you turn over the cards, and then the rumble and sound when you get a gold or legendary. I don't even know where to begin getting up to speed with "God Unchained", but I found some YouTube videos and will have a look at a few minutes of then in the coming days, after I finish my SM daily quests. Also, I am trying to find out if it's possible to link your Coinbase account to Gods Unchained. That would be idea. The Metamask thing is confusing. That's what I like about SM - the integration with Steem, and overall user-friendliness. The bottom line is that people won't use something unless it is easy to onboard...
