Is it just me, or did Bioware really oversell how big of an impact the decisions from ME1 would make on ME2? After hearing the Bioware guy on the Bombcast a bit before the release I was completely pumped to see just how different of a game two people could play, but after playing the game I am left hugely disappointed in their actual weight.
Just think about all the actual "big" decisions that carried over from ME1:
Killing Wrex: Aside from the bonus of having Wrex still alive in your game, the actual effect of the game is virtually nothing. All that changes is that Wrex's brother(I think) is the leader on the Krogan planet, he thanks you for killing wrex, then the mission plays out the same way. All that really changes is some dialogue.
Kaiden or Ashely: This one is just as irrelevant. All that changes is who shows up on Horizon, and that conversation lasts maybe 1 minute, and quite frankly, sucks.
Killing the Council: Probably the biggest fucking letdown of all the decisions. They are literally NO WHERE. They never appear in the game, never send you any kind of communication, NOTHING. The only time this even gets referenced is when you go to the Citadel, you hear some lines of dialogue about how aliens don't like humans now if you let them die.
Udina or Commander Anderson: Results in 1 dialogue tree and an email. What a letdown.
Killing the Rachni: Is this even mentioned in the entire game?
Anyway, ME2 was pretty goddamn awesome, but they dropped the ball in such a huge way on this part of the game. I don't know if they came up with this idea later on in development, and were unable to implement it as deeply as they may have wanted to, or if this is how they plan to do it for the rest of the series. Looking back I feel kind of foolish for thinking about the final decision in ME2 for so long after realizing how little the previous games' big choices mattered. I really hope Bioware pulls it together for ME3, because the way they described it prior to release sounded amazing.
