NUU is to be an open-source (massive) multiplayer game of space trade and combat: demo. That means it's free :P

It's not finished yet, not secure, okay for LAN and probably will stay that way for a long time ;) Still somewhat playable and I do my best to not break master :D 100% pure JavaScript in its current incarnation, runs a NodeJS backend and targets Chrom(e|ium) as the frontend.

It's excellent open-source cousin naev currently lends NUU it's assets. It's a very nice singleplayer game packed with ages of fun and it is still being extended and improved.

Like naev, NUU heavily inspired by Ambrosia Software's Escape Velocity. Still worth it's money.

A strong pointer to Spacewar! should also be cast, explaining the continuous efforts to enable gravity in a playable way :) (at least we have funkey orbits now :>)

The nuu project intends to use all the asset files according to their respective licenses.

nuu currently uses the graphics and sound assets of the excellent naev project, which in turn are partly attributable to the Vega Strike project.

All assets are downloaded from their source repo to the contrib folder during the build process and LICENSE information is copied to the build directory, as well as being made available in the client's about-screen and the server-splash.

Clarifications regarding commercial use

Besides the fact that NUU is not production-quality code and is not recommended for commercial use at the time being, you are - within the boundaries of the GNU GPLv3 - explicitly allowed to run and modify NUU for commercial purposes. This does not include any assets like images or sounds, which have their own respective licenses. Keep in mind to share patches to the source-code, uphold the license, and respect the attribution rights of the original authors of code and assets.

TLDR: This game is mostly an engine, any derivate engine must be GPLv3 or higher. Simple as pie.
