Ronin the company behind the Axie infinity has developed it's own blockchain. And it has started inviting new games and the dApps on it. So that they can be like Steam for the blockchain games. This would be building them for the upcoming marketplace battle that variety of chains are going through and they would be leading the battle of ecosystem.

Ronin twitter if you check regularly posts update on how new games are coming to their blockchain platform. For example, they recently added the ixels and it's one game that you can login to using the Ronin wallet. If you can check the below images you would get an idea.

and if you click on the Ronin wallet you'd find the extension and the option to login to the Pixels like that. There is always a phone and email option which is another good thing. Though i'd prefer Immutable passport instead of this as they offer too many login options there. 

I have learned from checking out variety of the authentication softwares out there that Immutable and few other game login systems out there, I find the Immutable passport much more advanced and also updating on regular basis. If you compare that with the Ronin wallet that would be kind of limiting.It just feels like walletconnect and trustwallet mixture added into an extension. 

If you are a game developer and want to integrate into chain then Immutable is a good choice. And also the wallet they offer is much better compared to the Ronin. You have very limited exposure on the Ronin chain and also Immutable and Gala are the leaders of the space so it helps if you stick with the giants for most of the things.
