-There are simply too many features that are needed to list them all here. We do however have a design document to guide development and what we want out of the gamemode. We desire many similar features of other RP gamemodes with just as many new approaches/features required.
-We want to approach this gamemode completely freshly. Tabula Rasa.
-Yes, like stated above this will be an entirely new gamemode. However, we have a script with many resources for reference.
-Like said in the OP, payment is entirely negotiable on a case-by-case basis.
-Other members of the staff shall be assembled once things are set in motion.
If there are any other questions feel free to PM me.
