Your examples don't inspire a ton of confidence. It's publicly known that Cryptokitties' usage numbers fell off a cliff.[0] I've never heard of Zombie Battleground or DelegateCall before but after doing a bit of research it looks like one is a CCG and the other is a Q&A site. Neither of those products need the blockchain to function and both are going into exceptionally competitive markets against deep pocketed, competent competitors. (Artifact, Hearthstone, MTG Arena, Gwent, Quora, Stack Overflow, Yahoo Answers - ok maybe not Yahoo)

I don't think there's any evidence to support the claim that such an application exists currently. I know Brave uses BAT, but that's not really their selling point if you are to believe their own marketing.[1]

I think you'd have to be a fanatic to think that there are rosier times ahead.
