Played some today and I can use a 200 length longspear with 86 speed without any turning restrictions. That by definition makes Mercenaries a better mod than cRPG.
No, but seriously, playing some piece of shit like Mercenaries makes you appreciate how many brilliant, but subtle changes have been applied to cRPG. cRPG has better hit detection, hit absorption by dead bodies, improved sound placements, reduced backswings, no sideswinging straight through teammates and buildings, no huge invisible hitbox on the right side of polearm stab, cavalry that is actually balanced, less ridiculous instahits, colour coded text in the log screen, a reasonably good score system and the list goes on.
