Loving the game, but things I don't like so far:
- Character whereabouts: Many a time you run into a major/minor plot character such as Ashley, Miranda, Grunt, Jack etc, but after a conversation with them you have no idea where they actually are in the game world. They aren't on your ship and they disappear after your conversation. Like where the hell did Wreav and Turian leader go that were on my ship? Kinda breaks the continuity for me.
- Free roaming planets: Maybe I haven't played far enough into the story yet but what sold me and made me LOVE ME2 was running around the somewhat open environment of Omega. The atmosphere and feel and sound of it was incredible, reminded me of Blade Runner. and what made that expereince more amazing was the other places to explore like the Citadel and the Asari homeworld and Krogran homeworld each with their own distintc feel. They felt like living breathing places with an atmosphere. ME3 so far has had none of that but the Citadel...why only the Citadel

Those planets are what provide such an idea of how the races fit into the ME universe.
- Weapons & Ammo: I've never run out of ammo with a weapon, and only ever switch weapons when I purposely want to use something else. I wish I
had to change weapons from time to time. ME3 tends to offer so many weapons now but half of them seem quite pointless, when will I ever get to, or more importantly
need to use a different assault rifle from another one? I wish there were some more clear cut advantages between them. Same goes for the ammo types, they all seem too balanced in terms of damage despite the perk of the ammo type.
