I'm going to bring forth the elephant in the corner of the room here:
Cyber Nations needs a mobile app
Fewer and fewer people use a full desktop computer, particualarily the "casual" gamer that Cybernations Targets. The few of us typing away on these forums are the exception, and a declining trend. The decline in CN userbase as a whole, as well as TE round by round, reflects this.
A good start would be a mobile-friendly/responsive design. I'd donate money to see all of this happen, as I strongly feel it will help bring CN back to its glory days.
