I started playing with the game editor in the pre 2.79 versions. It's Amazing how easy you Can Do cool little games. I find it much pleasant to use than unity, because blender is a all in one solution. The game player embed a python interpreter. It would be fun to use it to create a data visualiser. Unfortunally, theses pre-2.79 are not compatible with new Intel drivers for 520 and 630 chipset : selecting an object in a second layer make the software crashing. I found an old 520 driver, and it is working fine, but at this day I didn't find any driver version compatible with blender < 2.79 for Intel 630 graphics.
