I think most of the games suck. They lack great design, great gameplay and works like shit. Most of the times. If you compare popular games to crypto games, then crypto games are lightyears behind. Also Splinterlands just doesn't look great. The design has to be top notch for a game to succeed, and no crypto game has that. I think the closest is Gods Unchained or Eppics (CSGO card collecting game) But Eppics is not on blockchain, but you have the possibillity to put your cards on blockchain.
