Have you checked out EOS Knights yet? It has been pretty fun so far.

The biggest issues I've seen for blockchain games so far is cost of entry. Right now it maybe relatively cheap, but when you start gaining new crypto enthusiast during the next bull market it may cost more to get into a crypto game then it will to buy a brand new big budget game (60USD).

I've shied away from Ethereum games so far and am sticking mainly to EOS and Steem since, once you pay the "entry price" for the game, playing is essentially free.
