The game is somewhat fine as it is mechanically, what I expected was a hell of a lot more lore and story to what was going on. Story wise many plot lines randomly start or end and then are never heard of again once you move on, and most of these story lines come from shooting waves of bad guys while your ghost does stuff. There's one location in the game that so far you only seemingly visit in cutscenes, those cutscenes for me were what I wanted more of, and the location seems like somewhere I want to explore, but nope, here's some characters you'll barely see in this game.
I expected everything to be a lot more fluid too, joining fireteams is a pain loading out of the game and then back in, where was that fly in over head and appear in a friends team like try showed in the trailer. And speaking of, ships are seemingly all but useless besides just something pretty to travel around in, I thought before we got a hold of it that they might have something to do with how far we could travel.
All in all it isn't what I thought it would be, like many I was expecting more Mass Effect style lore and story for the SP, with thrown in MMO elements which would then open up the game in ways you don't usually get with more story based games. There is also in general what feels like a serious lack of varied content, I can't blame them for not launching on PC as I imagine PC gamers would laught at what they would get in the game compared to everything else out there.
That isn't to say I don't enjoy it, because I do, I want more of this universe they have built but they for some reason didn't want to give it to me in the game. I hope when they leave last gen behind and only have two platforms to work on that they will get more out the door in the future, more players in the worlds, more stuff going on, more lovely environments. There's massive potential, they just didn't use it as well as I would have liked.
