I've been working on and off on some additions. These are all small things however. I'm not sure if I'll release them at some point due to the overall quite limited popularity of the mod. Other than that I don't think anyone ever released a mod for skylimit
We play skylimit on my server - in fact it is the only conversion we play. If you compare that to other conversions then I would have to say as far as TWL is concerned that skylimit is the most popular conversion of them all!
I would make more maps for skylimit but it is a bit intimidating on many levels - mainly scripting and modelling.
I don't think there are many mappers that could make a decent addon to skylimit without JV's help.
Well i come from playing (and still playing) World Of Warcraft but before that i played MOHAA alot. My interest came back when i found JV's mod and i now made several people in my WoW guild exited and bought our own MOHAA server just so we can play it.
