PC, and Final Fantasy 12 is very similar in idea to this game fighting-wise. You have a group of characters who you can swap back and forth on the fly but cant actually control any but one of them at any time. You have to control the others either with pause functionality, or a tactics system that allows them to do a certain command if certain conditions are met.
Except in FF12 I can actually control my characters and attack without having to throw my keyboard across the room in utter frustration. FF12 EASES you into this idea, slowly giving you abilities as you proceed through the story.
Dragon Age Origins just throws you into the game with BARELY any kind of intro, gameplay-wise, and then forces you to try to acclimate yourself to a control scheme and battle style completely unknown to you except a few minor abilites you learn depending on what intro you start with.
And again, the Mouse/Keyboard control scheme is just absolute ****. You cant keep up with your characters or target enemies because your mouse-click does EVERYTHING. Theres no way to change how you attack without causing issues with your characters. Its basically an MMO if you didnt have a hotkey system for your basic attack. If I could just move that ability to a hotkey instead of using right-click to do it , it might salvage the game somewhat.
And once again your characters are dumb as BRICKS, doing things that make NO SENSE in the context of the fight you're currently in. The tactics system just does not work, and you're forced to try to salvage some simblance of a tactic with enemies who are designed to be fought by more than one person.
