Ok, I finished the tech tree in 1560.
What game turn is that? What difficulty level was this?
I find playing at Immortal that unit upkeep costs and such are high enough that the AI tends to be consistently ahead of me in tech, and that it takes hundreds of turns to get most of the tech.
I'm indifferent as to a future tech or not. I'd rather call it "future tech" than something magical though.
A better idea might be to create some super-expensive tech for each faction that does something nifty. Chaos civs will get the End Times which will let them win the game. Maybe Greenskins could get a tech that provides a +50% military production bonus. Dwarves could get something that gives +30% hammers in all cities.
Ideas for other factions?
This is not a high mod priority though.
