Quote: "As far as I'm aware, AppGameKit never even came close to DBP in terms of commands for 3D. It was like a cut down version which pleased no-one."
You are using the past tense, but AppGameKit is still being developed.
The next release is the first major release of 3D functionality. It has has 3D for a while, but the focus has been on 2D due to the demands of the mobile market. 3D on mobile was pretty poor in 2011 when AppGameKit was launched.
AGK is evolving like DBPro did. Compare DBP 2002 to DBP 2015 - they are different animals altogether. I would rather have an evolving product now than wait until 2025 for a complete product that will still be outdated by new technology within 12 months.
