I would like to have these additions for M&B 2:
Late medieval setting
Full, half and partial plate
RCM for vanilla M&B
Different fighting styles for the weapons. Diverse stabbing animations for polearms, proper staff fighting and good Zweihander animation like in the German RPG "Drakensang"
After you attack with a heavy weapon, you need to get it back into position which costs some seconds. Lighter weapons won't have this problem
More men on the battlefield. Come on, Medieval 2 features more than 4000 units on the battlefield even on my computer.
Squads and formations, shieldwall, pikewall, shiltron
Very huge genitalia laucher
Lances break after a succesful charge
Halberds, Bills, Swordstaffs, (Byzantine Flame thrower as a hidden item)
Ships for transportation, trading and boarding?
Ability to found a caravan.
Barracks/treasuries in castles and towns
More managment options for villages, towns and castles like in Medieval 2 or Knights of Honor
More and better quests involving sex
Minimum voices like in Morrowind where NPCs greet you (depending on their attitude towards you) when you come close, but the dialogue is text based. Best option for modders
Bigger map and bigger nations. I want a big capital, some free trading cities, towns, villages, castles, fortifications etc.
Ambushes by bandits
A real RPG system. I don't call for a combat system like KotOR, but I want realistic attributes, skills and proficencies and not the everything has 10 points arcade system.
I guess thats all for now.
