While I agree with you on some points, I would say that the biggest problem is not making proper use of these giant areas that they have! They have areas that are only used in one "story" mission and uh... Well that's it. Take for instance the subway station in Mars. That place is quite honestly my favorite area in the game. It's the only area where it is truly dark, as if the darkness actually has dominion there. I would LOVE to see there be a strike or just even some type of mission where you fight solely in the dark for 90% of the strike or mission, and hell throw as many enemies as you can at me the entire time! Things like what I've mentioned would add to the diversity of the game in a truly enthralling way.
