>OpenMW is a game engine recreation and only replaces the program. OpenMW does not come with any “content” or “asset” – namely the art, game data, and other copyrighted material that you need to play the game as designed by Bethesda Softworks. You have to provide this content yourself by installing Morrowind and then configuring OpenMW to use the existing installation.

The point is that it makes the game available on more platforms, more graphic features, stability etc.

1 - Having an open engine allows for enhancements.

2 - Having an open engine means opportunities to fix defects (OpenMW crashes far less than the original, even in its final version)

3 - You can recompile it for other architectures and operating systems, that weren't supported by the original.

4 - Someone could write a whole new game for the engine, and release the entire thing for free.

As a hobby project, I'm adding AI text generation to the OpenMW NPC's. I'm trying to figure out how this would work for a 'real' project without having to develop an entire game first.

I would definitely not be able to do that if OpenMW did not exist.

- Playing in 4K

- Playing on Linux

- Playing on a better implementation of the engine

- Changing what you don't like in the game

The code can be updated, adapted and audited. Or someone could provide alternative artwork and data.

What's the point of Linux when your wifi card driver is proprietary ;)
