Sharing a bit of my opinion on unit pricing, as I'm quite confused (097 test)
Just look at these prices (all from 1 city in England)
Norman Serjeants -- 2304 florins (!) ~ how about 1200?
Hobilars ------------- 1896 florins (!) ~ 800?
Archers -------------- 1338 florins (!) ~ 600?
Levy Archers -------- 433 florins (ok)
Spear Militia --------- 318 florins (ok)
Miles/Miles Pedites -- 0 florins (ok, feudal)
I'm confused because I don't understand such high prices on some units. They ain't supermen, their units size aren't numerous, yet cost as much as later full-plate professionals. As a player, I would expect pricing to hint me quality of a unit. It might not be uber historical, but gameplay-wise it's so comforting.
If I were to evaluate current pricing guidelines, it would look somewhat close to this:
0 florins
Feudal units
Upkeep: very high, 1000+ (just like already implemented)
100-300
Poor levy/Ad hoc units
Upkeep: half (no less, lots of men need to eat)
300-500
Units requiring some training (archers, specialized militia)
Upkeep: half
500-800
Cheap professionals, cheap cav, good militia
Upkeep: 3/4 melee and cav, half for missile units
800-1200
Decent professionals, ok cav, excellent militia
Upkeep: 3/4 melee, full melee cav, half missile
1200-1800
Good professionals and cav
Upkeep: 3/4, half for missile
1800-2200
Absolute best extraordinary professionals
Upkeep: half, 3/4 cav
Just tossing an idea.
