I'm personally excited for Catalyst (hype free roam), though I'm a bit miffed that they've allegedly removed gun play entirely. The skyline looks like so much fun to explore. Maybe they'll add a walk button so you don't look like an idiot in crowded areas.
I've also been following Battlefront DICE. It looks fun, but it doesn't have the same over the top crazy stuff that Battlefront used to have (on rails AT-AT is like a bad insult). Still, I'm a sucker for pretty graphics and damn, does DICE deliver on that front.
As for Siege, I'm interested, but it seems like they're trying their hardest to totally ruin the franchise name (hit markers and legal wall hacks to seize the "tactical advantage").
Just Cause 3 is going to be explosive. Spam that grappling hook; physics be dammed.
