To answer the question in the topic, that'd be me. I'm coming back to MonoGame. I went to Unreal Engine 4 for a while for my game, The Peacenet, and it worked out okay... but it's been getting more unstable and... one should not have to fight their engine.
Due to several engine issues we decided to go back to MonoGame. We're going to be reviving the Peace Engine, it's going to take a bit but we're moving back to MG.
Really happy to be back here after a year, guys!
