shift to zoom, being able to actually see your bullets fly cause they were black and they acted like crossbows, so you could aim above the enemy and see your bullet flying.
spontoon spears
skirmishers could build barricades
blundering people with up attacks
native facial hair, which they removed a couple to add cigars and etc. I was really dissapointed as the facial hair that I used in MM was removed for NW
copyrighted music which was way better then hearing WEDDING MUSIC randomly... lol wtf
baker rifles
France had grenadier skirms
jump attacks
360 jump attacks
spinning(unfortunately they couldn't nerf spinning without nerfing it in NATIVE+EVERY SINGLE FUCKING MOD THERE IS) like seriously you had to fucking ruin every mod just so your "DLC" could have spinning toned down like a tiny bit? kinda selfish.
only way to get a taste of how spinning was back then is to play with fire and sword, since it runs on and older warband engine that wasn't tampered by the NW team.
whats there not to like? Graphics? most people I know that play, play on lowest graphics anyways, I've been doing this on every game I've played multiplayer since early 2000's like Counter strike, etc cause gameplay>atheistic.
