I voted for programming the most needed base stuff for it, in one word porting to Vavoom things that were already implemented in KMOD, like leveling system, damage skins, NPCs, etc.
But to this I would add working on the storyline, since these two things are IMO the base we need for the rest of the things we'll implement, once these two are complete and in a stable state we can thn focus on working on maps, layouts, and everything else missing from it, that is going to be much faster to implement IMO, those are my two cents <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->.
