That depends on what you think of as half assed. DICE has never done anything remotely space sim oriented before. But they do have shooters under their belt. And those shooters are generally regarded as being pretty darn good. On top of that, this is their
first Star Wars game. We have no idea whether it will be good or not. You're perceiving this game as being half a game because there are no space battles?
So what you're really saying is, it isn't Star Wars unless I can pilot a ship. Isn't that like saying: it isn't Star Wars if there aren't Jedi?
And oh guess what... you can play as a Jedi.
There is nothing half-assed about leaving space battles out. I will only admit that to be so if the game ships with less content and less replayability than Battlefront 1 (which, by the way, I play more often than 2, because the ground combat was WAY stronger in my opinion). But from what I've seen thus far, DICE has given us no reason to believe that this game
needs space battles.
If you're not going to get it because there aren't space battles in it? Fine, to each their own in terms of taste. Saying that this will be a bad game because it doesn't have space battles? Pretty short sighted, my friend.
