sence I took a peak at the Air mod, i was thinking... why not put all the tiberian sun Buildings, Vehicle and Air units (seen the empty positions in the buy zone its obvious), maby a good idea will be to add Planes, Motor Bikes, more Weapons, modification for Weapons ( vehicles ) and Pistols.
this will give a very big boost (i think).
the idea i have is that with motor bikes you can use only things like uzi's (or something like that) and pistols.
and maby you can add options for ingame Build, Upgrade ( if map has an option previously added) to make walls and defences like the original Minigun automated defence from Tiberian Sun for nods and things like that.
also parachutes for air will be nice if jumping (kinda like Battlefield) and having the option of shooting while you are falling to the ground (dont know if its in at the moment due to lack of Unreal copies and i cant install it yet )
other things are backroads on maps so you can actually use the mountains and other parts of the map, that mostly are not added or are just not opened for access.
( I kinda just came up with those ideas and... havent formed them so good just wanted to post the idea getting started and thinked about ) cause its mainly the Renegade-X's team that can say the final words.)
