What are some weapons you'd like to see more of in video games?

dumbass those holes 2cm deep when have you every seen a sword with a blade 2cm wide

rapiers and foils, which were probably common dueling swords that someone would use a parrying dagger like in OP to fight with

Doesn't Mount and Blade have these?

No, sword breakers breaking swords is victorian era myth that paroted by modern day retards like many other victorian myths
