Dragon age=pause pause loadscreen loadscreen save save cutscenes cutscenes npc's voice conversations npc's voice conversations.
Atual playing is limited you mainly looks at eather cutscenes or freeze screen load or pause.
Dragon age is party game with many extremely small maps/areas and you play by pause game alot and give commands to your party memebers.
If you like to play like that then DAO is for you.
If you realy wanne play a rpg and build up your character by exploring doing quests find artifacts roam world but play constantly with your character and not constantly in a pause/loadscreen then D2 ED is for you:)
