Star Wars: Uprising Announce Trailer

^ Trailer for game set between ROTJ and TFA. Probably raises as many questions as it answers about the field of play going into TFA.

Kind of an interesting idea actually. Seems very political and since it's a mobile game I guess it might be very heavy on the plot as well. However I do doubt that this will have a big impact on the actual movie(s). Abrams and Kasdan seem to have written their own story pretty independently, and these games and other tie-ins will probably follow their story, and not the other way around. It will however be interesting to see how they decide to bridge the gap.
I also get this feeling that the Empire (or First Order) will have more of a guerrilla army quality to it in both this game and the new movies. The game even seems to suggest a form of Imperial rebellion against the Rebels. It'll be interesting to see in TFA just how much the balance of power have shifted since the OT.
