So some speculation given the revealed cards so far.
Different 'zones' to play cards in some of which modify game basics like we see on Ackbar giving you +2 draw in the reserve zone
Devastator has Resolve without Discussion. Something limiting table talk in a co-op game for specific cards definately makes for harder decision making.
Missions are time limited much different than the Lotr quests
Seems to be more a large battle type of game, perhaps not putting as much focus on Jedi conflict as previous Star Wars Games have
