Do you have any doubt about that? I think XMax will get a lot of developers and they will create even more DAPPs.
I think the main issue is going to be attracting them to come to the Xmax chain, there is a tonne of competition, and alot of people will simply want to stay with the big names like ETH, but I think Xmax will be able to do well.
But I think their focus is different; If they focus on the gaming side I think they could attract a decent crowd. Especially since your game rewards are actual tokens which can be used outside the environment.
There is a huge market available for game outside the crypto world and even inside it. Trust me this project got a good audience awaiting them.
THe games industry is massive so I think they wont have a problem in attracting people to this project especially with the DApp development tool kit built in within the Xmax platform
