Bringing back some of the guys was great, when archangel was unmasked as Garrus, I thought that was possibly one of the best moments of the game. Tali coming back was surprising but letting you romance her was brilliant. Those two moments really elevated the characters from just random team mates.
Garrus showed a much darker, dare I say sinister side, especially in his loyalty mission. I sooo wanted to see Tali's face, but Im not sure if I was pleased or disapointed that you didn't. Seeing her character so nervous and vulnerable made her seem a very real person. I usually romance her every playthrough, I havent with Jack though, I just dont like her very much.
How it all comes together for ME3 though....alot of questions! Id like to see Kaiden or Ash come back, Wrex as well. Given how 2 ended, Im not even sure if the Commander still works for Cerberus, he does turn his back on the Illusive man and steal his ship (Sorta) but the last dialogue option is "your on my team now" which to me suggests he still welcomes him as an ally.
We saw the reaper fleet and we know the odds he is up against. It would take the combined forces of the council races to make a stand. It would make great additions to see Kaiden or Ash lead the human forces, perhaps not directly but at least being the voice of them when it all happens. Wrex, Tali, even Legion, we have a major voice of the main and most powerful races weve seen so far. Theres alot of potential there!
