Hi there, First “rant” here, although it’s more of a question.

I have been working on a side project for some time and it has come to the point where I feel it might be prudent to protect my work with a patent or something similar.

The project in question is a multiplayer browser based game. The code is currently open source, but that can always change.

Given this is software people use rather than a service that developers might build off of, is copyright more appropriate than creative commons?

Based in the US if you can't tell and I'm above the age of majority luckily.

Thanks for any advice!
