Pityesz: The fix was promised but the multiplayer not during the time its GOG release. Your example is all wrong. It would sound more like: you buy a restored retro car. You bought it and it works. Then they say they will try to add a turbo engine to make it completelly unique. Since the original car's material was never meant for that it may work may not. Of course eventually it can be integrated but you have to wait for that.
I have no idea what that first sentence even means (not trying to be insulting), but the multiplayer was working for those who wanted it before GOG's "fix" (swbfspy/gameranger). Diesmon's metaphor is way more accurate: there is no extra "turbo engine" added here (multiplayer already worked) and there's no "integration" that's required for something already "integrated" into the existing system.
My point is GOG could've worked with the modding community to begin with to use the content that already existed to come out with a patch that was at least satisfactory. Taking 2 months to fix something that really takes half that to fix (or less, without getting Disney permission) is absolutely ridiculous, especially when there is compatible content that already exists and is actively being used.
deadmeow: No reason to complain. Let them take as long as they need to get it right.
If you don't want to wait, use swbfspy, gameranger or tunngle.
we had no reason to complain 2 weeks after it came out. Since we have had 0 communication from GOG on progress for an issue that shouldn't take this long to fix, I feel we are justified in our frustrations. Especially people who bought the game recently specifically for the new multiplayer.
