Are MMO’s possible for android using UR4 that uses teams for dungeon raiding and pvp?
Hello, I think it is possible, just think about controls in order to make it ergonomic. Think about performances too 
that’s such a large undertaking but 100% doable and has been done.
This weekend I and my coworker prototyped cross platform PC/Mobile in a twin-stick type game. No issues when performance is number one priority.
Id recommends just making something that you can test first to understand the complexity of it and go from there.

android app development MMO games have been gaining more and more traction the past few years, and for a good reason. The better hardware introduced in the last 5 years or so has really changed the possibilities for mobile developers, allowing them to create much bigger and far more ambitious projects.
Yes it can be done in a right manner.
