Highlander 说:
The hardest thing will be the gameplay. Unmounted battles with riflemen only is not what M&B is made for. The player always gets shot from a huge distance. That becomes boring after some time.
that's why we should pick a good story/history background first.

i completely understand that M&B is very good(or best) at mounted fight, big amount of fighting troops(not same as Total War), and the towns/castles/sieges.
like your 1866, there are also many many cavalries in WW2 china battlefield, and both sides of the war usually had to use bayonet, falchion, spear, katana to melee fight, because chinese army was always lacking in ammo. (not like germany US and russian, instead of bayonet, they use grenade, MP40, Thompson M1 and PPS.)
i believe i can find a good point to combine the gameplay and realization, by adjusting some tinny but important things like damage, accuracy, athletics......
at least i have already gotten much fun from my semifinished product

when all of my Klausure are finished, i will release a video, i hope it can be as good as yours
