[quote:1ausbag6]any support for 3D at all?
A part from the Box3D Object, Game Develop is not meant to compete with full 3D Development kit such as UDK or CryEngine.
[quote:1ausbag6]what features will GD have that in Construct are not implemented or focused on?
Game Develop allows extensions to provide new events types. Thus, ForEach/While loops can be made in GD by using For Each, While and Repeat events instead of standard events. There is also an extension allowing to insert and call function-like events. ( All of this can be made in Construct, but GD has an explicit support for different event type. )
I don't known if there is an extension for encryption in Construct, GD have an extension allowing to use AES algorithm on files.
I also have not found anything related to real-time image modification in Construct, GD provides some actions to modify Sprite's images at runtime ( See example "Destruction.gdg" ).
I plan to port Game Develop to Linux ( I mean the editor, games can already be compiled for Linux ). In fact, I have already released beta version of the editor for Linux ( As GD uses only portable libraries ), but there are a few annoying issues, like the keyboard which does not work when previewing a scene. But I hope to be able to fix it, in which case GD will be available on Linux. ( For the Mac port, I'm still waiting someone to buy me a mac ).
In the future, I will try to provide more objects and automatisms types. ( Note that even if GD is a freeware, all extensions of GD are currently open source, and available in the SDK. )
