Hi there!
OpenGames was created to create simple.
First OpenGames was created in 02.23(Feb) and was in dev until 08.23(Aug) because his engine cant support new features as scenes and etc. Engine for now broken (1.5.1) and most stable version is 1.3. We fix that later. For now more priority have OE 2. OpenGames 2 was started in 08.23(Aug) and still in dev.
Cheers with it and stay awesome!
