1. The compile time is nearly instant. IMHO, DBP isn't that bad. Especially when I'm working on a project spanning 10 source files with a combined total of 18,000 lines.
2. When building an AppGameKit app for Windows, the Player actually becomes your executable, but it's modified so that your game is the only thing it runs.
When building for other platforms, you basically do the same thing to compile slightly modified copy of the AppGameKit Player for that platform so that it only runs your Tier 1 bytecode file.
On the
KISTech Studios - Games Page there are 2 games made with AGK. The Getaway Car has compiled executables for both Windows and Mac, and I'm working on the MeeGo port right now.
