As the title says, since it’s really starting to look like the BGE is officially on its way out, it gives the impression that the sections dedicated to the engine will become obsolete.
My proposal (perhaps after the Discourse move is done), is to retool the BGE forums so as to make them open to showcasing projects done in all engines (providing that Blender remains the primary tool for asset and level creation).
In a way, you could have a section dedicated to the new interactive engine and sections for WIP and finished projects made in engines like the Interactive Mode, Unity, Unreal, and Godot. The resources forum could also be retooled to showcase the availability of pre-made assets and textures.
Would this be something to look at?
