As a new Sandbox 3D user i'm mightly impressed, however there are some issues that prevent me from adopting it as my 3D game creation tool.
1st) Lack of "proper" documentation and tutorials.
2nd) Is there a way to add weapons and dialog ?
3rd) Can Sandbox 3D create executable files (.exe)?
4th) How can i ad interaction in the game environment (opening doors,using switches etc)?.
I'm planning of creating a 3D exploration game with 8bit "retro" graphics and i'm wondering if Sandbox 3D is up for the job.

Thanks.
