Need I use XCODE to compile MAC and IOS version ,and VS2008 to compile WINDOWS version? It seems it's not good as Tier1. Can I use one IDE to release two kinds of versions?

If VS2008 can't build mac version,why there are ios libs in the platform folder?

I think I have so many questions to ask.

The ios lib is the player project I think.

The Platform folder is used by XCODE on a MAC to compile the iOS and Mac applications. Inside this folder you will see the various platforms we support divided into folders. As we add more platform support, expect to see more folders in here such as Android, XNA, e.t.c.

Thank you!

\o/ XNA!!!

So does that mean a C# Tier2 is incoming?

Everything is coming, just in a deliberate order Our ambition for AppGameKit is that we support a LOT of platforms with strong support for all the game-like functionality and ease you came to expect from DBP. We're working on Android now, browser technology will follow and onwards through the popular maze of devices out there. We have plenty experience with C# and XNA too, so we're not afraid to take on any platforms you can monetise your apps on.

Would be interesting to see how AppGameKit will look like on Windows Phone.

In Windows phone you develop using Silverlight & a version of XNA, and not c++, if i am right.

Nearly right, we use the XNA development system which uses C# (C sharp). It's close enough to C++, but has some basic differences which makes the code sufficiently different to thwart a simple code conversion. That said, we've managed to get the whole bag of tricks for a game engine running in XNA so it's just a case of clicking some blocks together
