There is a trend in next decade for blockchain based games, collectible+ VR games. At the moment we need to develop this industry and I think that volume now is too low as well as quality of games. But situation should change soon!
Ok. Who can explain what is the main advantage of blockchain based games? Why are they better than games on centralized servers? I can't find any reasons to play on blockchain. One exception is gambling. You can check that casino is not cheating (open source code) + guarantee of payment (blockchain) = good product. Other uses are absurd in my opinion.
