well I am working on a text based star trek game using c++, this is really fun and challenging. When I am done I will post it. Is it ok if I post here?

Sure. It's a game dev forum after all. But I think it goes into the Gamedev lobby. Good luck!

Sure. It's a game dev forum after all.

Except that copyright infringement is frowned upon and the site itself can't condone it.

:D

Paramount's rules for fan productions are there; adapt your project to them and you will probably be okay. Otherwise they may come after you, as they are fairly litigious with the Star Trek IP. Most of the guidelines there can apply to non-films, a few are a bit of a grey area (such as the duration requirements), so you still might be screwed. This is the only thing I'm aware of that they've released discussing use of their IP so it's your best bet.

You can post the source code of your game here if you want it critiqued. Otherwise you can post about the existence of your release in the Your Announcements forum.

If phil makes a star trek game that causes paramount to come after them I'll eat my shoe.

Likelyhood or unlikelyhood has, unfortunately, nothing to do with legality.

Plus now I'm tempted to tip them off just to see you eat a shoe.
