This is disappointing news. A decade ago I released three games using the Unity engine which combined got hundreds of thousands of downloads. There were a lot of bumps in the road (looking at you, mobile provisioning and constantly outdated API's) but the games were pretty solid and the developer community and plugin ecosystems were supportive.

I know Unreal is not immune to this happening someday, but I hope it won't happen before my upcoming game begins to sunset. There are other good engines to consider if it does...but my days of writing my own engine are well behind me.
