I know everyone is busy eating out this game's asshole but turns out I was completely right in my worst expectations regarding this game's unit behavior. In terms of how formations work, look, and play, it really seems like Bannerlord is to Mount and Blade what TW: Rome 2 is to Rome.
Specifically, they relaxed the unit collision such that units can now squish past each other and the result is this fucking mess:
This isn't just an aesthetic consideration. This affects movement, combat, and maneuvering - soldiers hug each other when they run, blob up in formations, and compress themselves into a single ungodly line when charging because there is no weight behind the ranks. As such engagements are clusterfucks where flanking is trivial (since there is no depth to the units and way more men than should be possible is able to squeeze itself into the front line) and second-rank weapons like polearms, spears, anything don't have a place because there is very rarely, if ever, a second rank.
Bonus meme: the above screenshot is from a single custom battle, my first engagement in the game. I spawned in 100 Sturgian spearmen against 100 Imperial Legionaries. Both units - including the fucking *spearmen* - fought exclusively with their arming sword sidearms. Nice to see spears not only being useless in the hands of NPCs but blatantly disregarded by them - we have reached peak Mount & Blade, lads.
Eight years for a step back.
(To be fair to the game, the new recruitment, politicking, and Influence systems directly address some of the concerns I personally had with the strategic layer of M&B, so perhaps I will find it a step forward in those areas - but if the battles are worse, what does that matter?)
