Hi friend, I started my "second life as a game programmer", after programming games wit TI99/4A and arcaic PCs in the eighties, with DarkBasicPro (after doing some games with Visual Basic and Java), see my web site http://darkbasicgames.altervista.org/
After having made 5 games and some support libraries for sprites (similar to some AppGameKit commands) and tiles, I reverted to AppGameKit in order to try to sell something in the mobile markets.
So I was in a position similar to yours. I found myself at perfect ease with AppGameKit, having had an experience wit DarkBasicPro, so I advice you to buy it strongly.
Consider that AppGameKit uses OpenGL libraries, more portable, and free from DirectX versioning issues that make sometimes a DBPro game to work on a given pc and not on anothers.
The trial let you play the app only on the PC where AppGameKit is installed, and of course you cannot create packages for Android, etc.I have 6 apps on Google Play (search for Texasoft Reloaded), and there are a lot of apps made with AppGameKit by other people (have a look at the gallery in www.appgamekit.com). So you should be convinced the AppGameKit works well and let you produce the apk files. I use only Tier-1, but Tier-2 should work well too.
Considering the it costs only 59$ (a real bargain), all doubts should be cleared.
