I think it's cool to incorporate blockchain into video games. My favorites seem to be similar... I really like PVP and fantasy type RPG like casters/stealths/swords and stuff. But I also think the gaming market is tough. Lots of competition and all these small niches where pockets of players exist. It just means that developers have to be careful if the intent is to remain profitable. My experience with kitties was that it was too expensive and I didn't really see a reward. Maybe I just was unlucky or didn't understand a strategy but either way it was just a turn off and I haven't had a second look at blockchain games since then. I expect that if blockchain games do take off it will be more so that the blockchain isn't the main feature people look at... it will just be in the background.
For me, the main click of blockchain-based games, that it could be self-sustaining, if i can say so. Obviously, they will be pay to win (or pay to play in pleasant environment), but the fact, that you actually get the money for playing; money you can spend in said game, make those kinds of games interesting to play and be competitive.
