I really like NTW and even there are lot of inaccuracies, and it's more of a copy or an upgrade ETW still one of the best Napoleonic games. Today is little bit outdated and need new N2TW game. The greatest lesson i would take from WTW and W2TW and even little bit from upcoming W3TW. There is some ideas what I really like to see.
The army could have now 30 units. And in one battle player can control up to 60 units.
There could be some legendary leaders like Napoleon, Blucher, Alexandr, Welington etc..
Next will be smaller heroes - generals like Ney, Murat, Gordon, Kutuzov (oriented on supporting cavalry, artilery, infantry, can get horse or some kind of body guards) etc..
Leanders and generals will be finally more useful in battles not just hide them behinde hill or building (could be killed but can obtain skill to only be wounded 20lvl)
next smaller heroes could be ammunition wagon and Ambulation wagon
Ammunition wagon - non combat unit- near artilery add ammo, little bit increase fire rate, etc.. Even could resupply ammo to infantry? (on the battlefiled if destroyed could with big explosion kill nearby units
Ambulation wagon - non combat unit - heal nearest infatry, if in army increse resupply of lost units and after battle recover small % of lost units
The spy and aristocrat can be like in NTW but with skill tree.
All legendary leaders and generals will have skill tree like in Warhammer series. Both generals and legendary leaders can lead army. Generals could be in legendary leader army.
More units for example in french army not just grenadier, fusilier voltigeur and chasseur.. but whole infatry types.. line infantry: grenadiers, fusiliers, voltigeurs and light infantry carabiniers, chasseurs and voltigeurs.
Line infantry is for line battle average for melee combat average for fire (grenadiers even better in melee and voltigeurs better in fire line voltigeurs can skirmish) And light inatry worse in melee comabt better in fire (carabiniers better in melee and light voltigeurs better in fire and can skirmish)
Line formation, colum formation, square formation and voltigeurs (jagers, riflemans, etc..) skirmish formation
Guard units will be like regiments of renown
Commander, musicians and flagbaerers will be behind lines not in first line just like in history (like in Cossacks 2 Napoleonic wars)
Canons will have limber and will be little bit faster = useful. Crew can abandon canons and hide for example in square. Canon can form formation with infatry to defence square (like in battle of Pyramids on the corners of square) . And will be more accurate.
Cavalry will have fire weapons..Drgoons and chasseurs a chaveal will have rifles as normal in NTW and Cuirassiers and rest cavalry can fire (around 4 shots) for close range with pistols could help agains square formation or another cavalry.
Very nice could be regimental colours for all units and add limitations for some units like french horse carabiniers can be only two.
Regions will have more settlemets. Could be build walls and fortresses. During sieges could be build defensive buildings like baricades and spikes etc.. Diplomacy can be upgraded and can coordinate allies like in W2TW
And uniforms could be more historical and more realistic..not ammo pouch stuck on their ass but on the ammo pouch belt
Grenadiers and voltigeurs could use their sabers not just bayonets (voltigeurs very often even don't have bayonets).
Hope for returning of historical battles and period campaign (Egypt, Italy, Europe, 100 days..not just one battle). All historical battles can befight fromm all sides.
Well it is just quick idea what could be change and what I would like to see in N2TW and I know in Total War series can't be all historicaly accurate like organisation in battalions etc.. but with these upgrades everybody can fight like this ..with all this added missing units, regimental colours, generals fighting with their soldiers more flags more drums and cornets, more fire and smoke...
What do you think..could it be better or do you have some same or different opinions?
