Just a thought here Ferali , but how about a new Version of Siege ^_^
instead of pretty little diamonds and boxes , you could design some kinda advanced Mechanisms which players could interact with in order to protect the bases ...
combine this with the ability to use NW3 as well as std Weapons I think this could be quite popular?
you could even make your own JetPacks and perhaps even include the Vehicles from your other pack
anyways , just a thought.
