Eh. I dunno about that idea - after all, its us brits who have the best counter terrorism units. I think your economy and cultural dominance are your strongest trademarks. Maybe having the following:
- larger national boundaries
- quicker extraction of oil
- tanks produced cheaper
- extra resources from caravans when they visit allied cities
- cities assimilated faster
Unique units could be stuff like...
-Sherman (modern) - cheaper than normal tank
-Black hawk (information) - kinda like a aircraft carrier, only its a chopper not a ship and an infantry squad instead of planes
M1A3 (information) - stronger, tougher, more expensive than normal tank
- Native warrior (ancient - medieval?) - light infantry
- F16 (information) - stronger fighter
Aircraft Carrier (modern) - has 1 more plane than usual, more hit points than usual carrier.
I never really use planes so far. I find that a healthy mix of infantry, tanks and a whole lotta artillery does the trick for me. Add in a few supply trucks and anti air if i remember and i'm done. Planes are just a hassle, what with range and airfields and so on. By the time they reach the enemy force your tanks will have leveled it. But i do find that 13 or so of the strategic bombers will reduce a city instantly, meaning your infantry can take it and set up the campfires.
1 thing i find is that i don't like the games where everybody starts in ancient and progresses to information. You spend all your time desperately advancing epochs. And i think it is too easy to do so - you should have to plough lots of effort into it, not do it inbetween tank batches.
Also, it really really needs ways to speed up infantry. I'm tired of sitting around waiting for the little buggers. Thats where the railroad idea came from.
So do you fancy setting up some games?
