It would be appreciated to at least have a reason behind this decision ?
I assume it's cuz they'd have to code it from scratch.
This really. It's not as simple as just "hey here's commerce!"
This server is based off of G13 server files - meaning commerce is literally not implemented.
In order to implement it, we would have to code it completely from scratch, using game engine elements that aren't even implemented - which we'd have to implement ourselves.
I should mention that we do not even have the source code, only pre-compiled binaries. It's really hard to modify a program without the source code.
Realistically, it's simply impossible to implement commerce.
