So since it's coming to PC... how is this compared to Dark Souls? And is there an overload of weeaboo shit such that I'd find it unplayable?
You can't really compare the two. Two different beasts.
To start with, in Dragon's Dogma you're get to a party of 4 in half an hour of the game start. You get to make your own pawn and then recruit other 2 pawns from the internetz (other people's pawns). The gameplay is more actiony then Dark Souls specifically because your character has more movement options you can set up combos with your pawns.
For instance you you get downed by a wolf (and it will happen at the start cause they are quick fuckers who like to pound on you from outside of the camera view) and your pawn will kick it off you and pick you up. Hell you can pick up other pawns and carry them if you want.
Warrior vocation can use their shield as a trampoline for you or you can do it for a pawn (that is a skill), in a fight against a flying enemy if you haven't got a bow or magic you don't need to wait it out that way, just bounce off the shield of your bro and reach the bastard, then start slashing/punching its intestines till it can't fly no more, very satysfying.
The game can be hard (regardless of the difficulty setting) especially when you encounter new enemy types or if your pawns don't know well the enemy, or you get surrounded, or when you stay and fight when you should avoid it. You see there's a tiered system of knowledge for pawns based on stars, they get one star by encountering the enemy (if your pawn gets taken out by another player and encounters enemies he will retain the knowledge), second star is when they kill a set amount of them and thirs start (mastery) is wehn you discover casually effective ways to dispatch enemies.
The difference between 2 to 3 star is immense: once I picked up a Strider (daggers, bow-arrows agile climber) pawn that had 3 stars vs cyclops and she killed them so quickly that the first time I was like "what the fuck is she wielding? end game gear" instead it was that the AI knew how to exploit weak points and went to town.
Depending on the Vocation you choose the playstyle changes and it can be harder or easier vs different enemies. As a melee charcter fighting Death is not easy (semi-random night encounter) because you can't really grab onto the Grim Reaper as far as I know but as a ranged attacker is easier. Keeping enemies like ogres at range is hard because they are nimble fucker who like to target female characters and if your sword and shield pawn is female it's good cause they will focus them and you want that but if it's your sorcerer that is female.
I'd say Dark Souls is more slow paced an methodical overall, if anything because if you fuck up there there's no pawn to cover your ass but you can also get oneshotted by enemies if you don't know what you're doing.
