Hello Ray, Thanks for answering
Beside the usual In-App-Purchase stuff, the most important origin of revenue is a trio of services: Applovin + Chartboost + RevMob. These three represent 75% of our earning (it’s the same for most indies), so their implementation is paramount to use UE4 to deploy on iOS and Android. In addition to those, Fuseboxx is another we use a lot on mobile.
I know that we could start producing plugins for that, but, beside the fact that it’d be great to have them out of the box, reading the forum I see that there are crashes trying to work with C++ to Java implementations (necessary for Android), so anything you are able to give us in the enginr itself would be really a great jump-start
