So, you have a general. You hire an army.
And you wage war, crushing the opponents, with never any losses.
And 40 turns later, your general dies of natural causes, while your PEASANT UNITS stay as veterans, and can still live to the rest of the campaign, always getting stronger.
I like how my archers have a way longer longevity than my finest general. Actually, they're immortals. Fuck yeah. Even better, the longer they live, the better they get. I can already picture the 80 years old sharpshooter, running around the battlefield.

I seriously love leveling up some generals, but one year per turn means you'll really have to always be in war to profit using them. A shame. 0,5 year/turn would have been lovely.
