Well written post!

I don't care about loom network having a whitepaper. Loom network convinced me with their projects. I enjoyed learning solidity with cryptozombies.io so much I even donated a portion ETH. (my review)

Zombie Battleground makes a very consistent first impression. Some say it is heavily based on Blizzard's Hearthstone, which I can not rate because I don't know Hearthstone good enough.

Actually, Zombie Battleground was intended to be a game template for developers. Referring to something well-known on a template is understandable. Hopefully the finished game will differ from Hearthstone.

However, for me the crypto related features are reason enough to support the project. They are currently running a Kickstarter campaign to make the game known in the not crypto world. I can not wait to test it and got early-access codes for me and few friends.
