From the trailers and info both games look good enough for mobile gaming market. I've played Dozerfriends game from Playdapp which was also good. So I think these games will also do fine. Only thing missing is that there is not much info about the blockchain elements and monetization or play to earn mechanisms.
It's a gradual process, very soon playstore will be full of Blockchain games, the thing that makes blockchain games more fun is the ability to earn while paying, something worth devoting your time for
