Destiny is out tomorrow, but the servers are live today for people who got their copy early or are reviewing the game. I've had a chance to play quite a bit already (more on that tomorrow), but I wanted to touch on one thing in particular today -- Remote Play.
Often times Remote Play is a second thought, and requires you to make some sacrifices in control quality, but Bungie did a great job adapting Destiny for the Vita. Everything is relatively the same except for of course the absence of two buttons (L1 and R1) on the Vita and the ability to click the analog sticks (L3 and R3). The former is solved with very intuitive tap system -- a tap on the left side chucks a grenade, and a tap on the right allows for a melee attack. The sprint button is the down d-pad direction, right next to the left analog movement stick.
