ahhh.. yes, now I understand.
Now I understand.
So I was wrong. You can have a version "total conversion" along with an original game (or a MOD) in the same PC because they are two different installations.
As to the second question, I'll have to wait a MOD for use it.
ok..
Thank you very much for your help!
Kind regards.
Not exactly. The Freespace_Open engine needs two things to run:
1. An executable (e.g. an exe file)
2. Data-Set - models of ships, textures, mission files, table file that describe how things act in game. In retail and finished MODs/Total Conversions these are normally packed as vp files for easier managment.
By now, you can tell FSO to run with whatever Data-Set you want. Just click the "MOD" button in launcher and select the directory of the Data-Set you want.
This could be the Freespac MediaVP folder, in which case you're using files that contain community upgrades to the retail Freespace assets. It could also be a MOD, totally new files created by someone.
When you're no longer using *any* files, from the retail version of Freespace (files released with the game back in 1999), then you're effectively playing a Total Conversion, since beside the engine itself, you're not using anything related to the game.
Why the distinction?
Freespace has an open source, non-commercial license. People can tinker with the source code and build versions themselves. They can distribute these executables, as long as they do so on a non-commercial basis. However the actual game assets are still under copy-right and can't be distributed in this manner.
So if you create a campaign, or game that uses assets from the retail game, end users will need to buy a copy of Freespace as you have no legal means to distribute (all) the necessary files.
If you don't use any assets from retail, you can pretty much distribute the game as you see fit - and as long as you do it on a non-commercial basis - since all asset files are your creation and therefore you have copyright over them, and the executable (the engine if you will) can be distributed on a non-commercial basis. So a Total Conversion, unlike a MOD can be used by people without buying a copy of Freespace.
