The majority of the zones were repetitive copy/paste, something DA2 gets criticized for yet people turn a blind eye to here. Only the few important storyline areas are different, and nothing special at that.
Along with that, gameplay was very repetitive as well. To the point where it was not fun at all towards the end. AI was pretty dumb, both enemy and friendly, which didn't help.
Character development was mediocre. Halfway through the game I stopped caring what I put points into and just let the game do it itself. Towards the end, it felt like it didn't matter.
Very easy to get the best gear.
Completing all the side missions felt like a chore more than anything. Gave up on completing everything.
The stories were mixxed. Some were decent, some were terrible. I feel like the "Spectre" position was created specifically to justify allowing you to run wherever you pleased and doing as you pleased. The overall story was average. By the end, I felt like it had not progressed very much for the amount of game time. I suppose doing side missions pads the game time vs story development, but then if you just focus on the main story it would be a very short game. The story of your companions I absolutely despised. Most of your companions' reasons for joining you basically boiled down to "Hi! Want to help me?" "OK LOL!" Just look at Wrex. He joined you because you were after the same person, and then he just stays with you? Its like they just gave up once they threw him in your group.
None of the characters felt like they had any depth to them. They might develop more in the later games, but they had this entire game to do it and nothing happened?
I got 1 and 2 together during a sale around the time 3 came out. I never installed 2. Like I said, there are certainly worse games, but there was not a single aspect of this game that wow-ed me, and along with the huge hype train behind it, was a big let down.
