I think it would be a good idea if you continued your work with the skirmisher.
Just the stargate mod alone has about 200 regular day-to-day players, not to mention the people who drop by are around 1000 when we release something.
There is a Halo mod in production, altough it didn't go public just yet, but the author has quite many ships modeled.
OldDragon is making is Nexus: The Aurora Affair mod, which is great so far, and many of the community will love it.
So there is still community out there, and there are still a lot of people who would appreciate a new, improved skirmisher to play their mods/nexus battles.
And the skirmisher is a very powerful tool for the players, makes our mods 100x playable, taking into account that a good mission takes a long time to script.
My ideas for it:
-The ship positioning ui would be a good idea, although i don't know if it's doable, maybe you could salvage parts of the mission editor.
-A bit more self-explanatory UI, as many people don't take the time to read the FAQ you post, or the one i write to the readme of our releases.
-The mission numbering is the thing that most people tend to frak up, and not just because the lack of reading the FAQ, i too make mistakes with that sometimes as i always forget what number i gave to my last mission. Maybe turning that into automatic would be a huge leap. (It detects what mission numbers are taken, and assigns a non-taken one automatically to the new mission)
I'll keep thinking about other useful (and sometimes crazy) things, and i'll add them to this post later, as these are the only ones that come to mind right now. I know that merging mods is unfortunately impossible as that needs a lot of copypasting of models and textures not to mention extensive edits of the tactictypes.ini
