If you have a Steemit account, and haven't tried Steem Monsters(https://goo.gl/4D7jwP) or Drug Wars (https://goo.gl/JUXbGw), then what are you waiting for?
These are great use cases of what gaming can do on the blockchain, from the ground up. Everything is linked to your Steemit account and all the cards you get in Steem Monsters you get to keep and do whatever you want with them. You transfer to another player, sell them on the market, and now even loan them to another player for loan payment?? What? this is a far outcry from games like Hearthstone or Magic the Gathering in my experience.
In the case of Hearthstone, everything you invested in the game you can not transfer or sell it back if you decided not to play any more. In traditional card games like Pokemon and Magic the Gathering, they are very hard to trade between players all over the world, and the only market for collectible cards are pawn shops, or comics and collectible stores.
The use of blockchain and an social platform, Steem is really position itself to be the earliest adopter of next generation of blockchain gaming. The ease of acceess, as in any browser game, and yet deep and engaging enough to keep me coming checking for more. The "grind" of leveling your cards (Steem Monsters), find the best strats(Drug Wars), and moving up the ranks now feel so much more rewarding as you can see your collection's value.
Non-gamer investors can find the market in Steem Monster to be enticing enough to buy up some rare or legendary cards now before the inevitable rise in blockchain gaming. I highly recommend these two games to all games and investors. Steem Monsters(https://goo.gl/4D7jwP) Drug Wars (https://goo.gl/JUXbGw)
