DA: I will have multiplayer but it will have NO effect on single player and all DLC will be free. They will be going with a sort of microtransactions approach that F2P games use, in which you can buy, with real money, random chests for items.
This all sounds quite good, especially with the 20-30 miin. MP missions they are aiming for. Furthermore, your MP characters are just that, character that will have banter during missions. Essentially, you are playing as agents of inquisition.
