Yes. Things they changed from classic AC that I like: The assault-flight mode, the cooldown-based weapons, mouse and keyboard controls, some difficult and interesting bosses. The fact that you don’t have to pay for failed missions. Removing stunlocking.
Things I don’t like: fast rotation, loss of radar, general sameyness of the ACs compared to the more extreme oldschool designs. Sometimes it feels like the only important decision is “twogun or sword”.
Things I’m not sure about because they’re obviously “Sekirobot” but the old AC approach had some flaws: the new energy model, the boost-dodges, the new stun model.
Things about oldschool AC I’m disappointed still haven’t been replaced: The fact that buy/sell/install hasn’t been unified into a single screen instead of jumping back and forth between 3 screens. The fact that you don’t automatically start skating by default - why do you ever want to walk in modern Armored Core?
It’s a good compromise between Souls and AC, but there are definitely things I miss about the early games.
