I'm still using UPBGE 0.2.0 BTW!
Till this day and its still holding up really well. and I even have a new updated version of the engine now to test more newer implementations.
My goal is to get some of the API changes i made in to the future legacy builds or atleast have them remade and built in to the latest future versions of UPBGE 0.4x and beyond.
