vear: Thanks for the indepth comparison.
To push the matter even more - do you know if anything was cut from the newer release (the way it sometimes happens with music, censorship and such), or the re-release is just "purely better"?
Since 2005 i have been maintaining and developing Original War (With help from the community and full source code) on a volunteer basis. As such Original War is practically immune to censorship(Even if it was censored someone would make a mod to put it back in). Basically i can work on what i want when i want, i am not being told what to put into Original War or what to take out. I make patches and Bohemia can use them or not. So far Bohemia has only rejected patches based on them finding bugs. Bohemia have never asked for any censorship/etc.
In relation to music Original War was made at a time when development studios had their own staff to make the music. They were not licensing music for X years and then never renewing.
The legacy edition only exists due to the minimum requirements changing. The reason there was no patches released officially after 2.0.6.143 is because SGUI (The new GUI system i developed) required alot of time to replace the old interface system (SGUI was started in 2015 but was only focused on since 2018). SGUI is a modern GUI system which uses OpenGL, it can't work with Direct Draw as its very old. As such Direct Draw Renderer was removed, and it was a fallback for older computers.
The main benefit of SGUI over the previous GUI is that the previous GUI was set in stone. You couldn't add anything. You could only move elements about, resize but that was it. SGUI uses LUA, as a result 90% of the GUI code is in the LUA text files which can be easily edited. There is also bridges between LUA and the maps scripts, allowing data/commands to be transferred between the two, this allows for a maps script to trigger SGUI's lua code and vice versa (So for example a map event can trigger a custom window with a puzzle, if you solve the puzzle then some good event happens in the map, if you fail a bad event could be triggered in the map).
One of the best examples is Cards Mod (which is still a Work in Progress):

The following is a silly Myst Parody i made to test some SGUI stuff (it shows some modding freedoms):
