I think that there should be a type of "Sub-Tech". They don't cost as much as normal techs, but do give major improvements. For instance, "Rifles" can turn into "Sub automatic rifles" for a large damage increase, or "Flight" can turn into "Commercial Flight" for happiness, and the airport, and so on. They just give bonuses to whatever you have.
Nukes-
There were MANY, MANY stages of nuclear weaponry after it was created. I think the nuclear bombs should be able to be upgraded on their own, like in my sub-tech idea above.
Fission - Allows "Nuclear Bomb", which takes out 1/5th of the units combined health, includes the destruction of units, but it has to be carried by bombers, and has a 20% chance of destroying buildings.
Then it would go on to a larger nuclear bomb with research(1/3rd units killed, 33% chance of a building's destruction)
Then, it would go on to nuclear artillery
Nuclear subs
Nuclear missiles, which makes our ICBMs we know.
MIRVs, which can hit multiple targets at once, kills all units in a city, but takes quite a few hammers.
Finally, you can get the H-Bomb, which should be able to be reached a bit faster, it completely obliterates a city.
I also think nukes should cause a lot more war weariness too. 2 nukes caused the Japanese to surrender, so why do I have to spend my time on 10 super fission bombs(500KT each for a ICBM, I think) just for them to THINK about it?
