Blender 2.80+ Game Engine Replacement with Python I was mostly using Blender for simulations and interactive visualizations controlled by Python. Now 2.80 REMOVED the Blender Game Engine with no replacement!!!!

Really not cool to remove something that was there for decades with no replacement! I have checked the external game engines but this is not the same - I need to export/import and write in some funny languages while I had everything at hand in Blender :-(

Belnder became just a 3D modelling tool :-( 

Is there any way so I can perform a live real-time visualizations that are Python controlled in new Blender 2.80+ ? I don't really need physics (but the collisions would be nice to have).

Any hints welcome.. or I need to stick to 2.79.
At some point in time, an "interactive mode" was in discussion/announced. But it seems this was dropped, according to a statemen at Blender Conference 2019. You can check some discussion at Blenderartists:
