I see people mentioning Mass Effect like it's a bad thing. A Mass Effect feel is a good thing, in my opinion, and I definitely got that sense to a degree from the footage, jjust from the first person point of view. The main difference with Mass Effect, though, is that to me Mass Effect comes off looking a lot more fun. It just works really well with the game's cover system, and it feels like my actions have more direct significance, whether it's changing bullet types to hurt a specific kind of enemy (which I'm not suggesting Destiny doesn't do), I can order teammates to go where I want, and to use certain abilities, and then coordinate with my own complimentary abilities.
Mass Effect has a more strategy based feeling all around even when you're dealing with enemies that don't last super long. Having cover based shootouts with these enemies makes it feel interesting. It feels like there's a nice tug of war between you and the enemies, and actually hitting your shots on enemies in Mass Effect has always felt really satisfying to me. Mass Effect 2 was obviously a big improvement over the first in that regard. I love the visual feedback you get when you're hitting shots.
You know, before even finishing this post I'm watching it again, but this time completely thinking about it like it's a first person mass effect, and I actually like it a lot more now.. go figure lol. Also paying closer attention to the use of abilities, and I'm liking what I see. The enemies may be going down easy, but then it's obvious there will be more tougher enemies also to mix things up. I wouldn't mind getting a bigger window into the story or narrative of the game, however. I've totally flipped my opinion of the game now that I see it as first person mass effect.
