I thought the game was pretty bad.
Got over the novelty of flying pretty fast, big world but you spend most of the time flying from point a to b and that makes exploration nearly non existent, not that there would be anything to explore, the world just seems huge to allow you to fly, it never felt like it was packed with secrets or anything like that. Free roam felt dead.
I didn't like combat either, guns look and feel stale, and from what I experienced the combo system is pretty much "wait til your team mate uses their ice ability and then use your lightning ability" = COMBO. Enemies are dumb as hell, and they were hard to spot too, and I guess that make up to the poor enemy a.i at higher difficulties they just cranked up their shields and made them having pinpoint accuracy at ridiculous distances and angles.
Getting loot didn't feel intuitive or exciting, you grab these tiny little colorful orbs then wait til the end of the mission to see if you got anything worthwhile.
Also, content was not really compelling, when I was told that that "stronghold" is gonna be end game material when the game launches I laughed because I thought my friend was joking, turns out he wasn't. Shit wouldn't even pass as a "strike" in Destiny.
oh yeah, and I didn't care for anything that was happening or being said, and the first person perspective in the tower felt horrible.
game felt like a 2014 game or something. pretty trash.
