Just joined the forum and thought my first post should contribute to bridging between the two communities. I found GamePlay3D after looking for a free and cross-platform game engine.
Being a Blender user I had mixed feelings about BGE. I love its ease-of-use but I really wanted something I could use on any platform and without licensing restrictions. Unity was another option but it just didn’t look lightweight enough to my taste.
If you haven’t heard of GamePlay3D, be aware that there is another very usable and highly maintained game engine you can use with Blender. You should also know that the GamePlay3D community is struggling with some issues revolving Blender’s FBX exporting and axis system.
I think that in the long-run, the two communities can profit from “blending” together
