Yes, this is the correct place to post.
Welcome to the forum, DavidAGK!
I recommend starting with AppGameKit v10819 (the final V1 version). It is fairly stable and works well on most devices. AppGameKit V2 is only in alpha mode and not complete (and the iOS and Android and Tier 2 stuff is not ready yet).
If you are comfortable in C++, Tier 2 is a great way to go. It allows you to use all the standard classes (std::string, vector, etc.) and object oriented programming, of course.
Tier 1 (AGK Basic) is also quite good for final production, as well as reasonably quick prototyping.
There are a lot of people here who will be willing to help with issues. Starting on 11-Jan, I won't be anywhere near as visible as I used to be (I am starting a full time job in Anchorage, Alaska).
Good luck and Happy Programming!
