The FMOD dll is a third party DLL, nevertheless, I would provide the source code for accessing the DLL. Is that still okay?

No thanks

This is JCL's answer:
"Can we use plugins? - Yes, but only when including the source". The problem with 3rd party dlls is that they can include all sorts of resources. While I know that you are a serious engine user, some might hide resources in their dlls.
Send your project (including the source code for your dll) and the fmod dll. I will then download the dll from fmod.org and overwrite the fmod dll that comes with your project. This way, everyone will be sure that there isn't anything hidden inside it.

Very interesting contest indeed can't wait for looking demo

I have an idea but I'm not entirely sure if it is allowed in this contest:

A web browser programmed in Lite-C that downloads htmls and interprets them as would a normal browser. The TWIST is that it does interesting things with the content such as displaying it in 3D or animating it. It would also use special tags ignored by other browsers to allow pages that can be 3D environments/levels defined in an HTML-like fashion.

Would I be allowed to
a) Download HTMLs
b) Download models and compiled levels
c) Use a DLL for which I don't have the source or did not create myself? (like GSTNet or the webaccess plugin)

b) Download models and compiled levels

make the game normally, then download all models needed at start. The point of the contest is gone.

I'm afraid that you can't download models and levels; the game is supposed to create what's needed at runtime, not get it from another computer.

That makes sense. What about A and B? I would think that downloading HTMLs that I didn't post might not go against the rules as they'd be more like a form of input than part of content.

Downloading html files isn't against the rules; however, running code on a website using the engine won't get you too many points from the jury.
Using DLLs without posting the source is ok only when:
a) They aren't yours, but they are well known and don't contain any other resources;
b) I get to overwrite them with the latest version from their website, in order to make sure that they aren't altered or replaced with something else.

Are we allowed to use external save files?
They aren't needed by the game, but it's nice for the player to save the game...
Otherwise, I would tell the player, that he shouldn't shutdown the game before he had finished it...
EDIT: sry^^ Have read your answer, george
