I just finished my playthrough, doing just about every single side quest and finally getting the Completion achievement where you finish the majority of the game
I've played this through I don't know how many times, and I finally got it. I ended up doing the Liara romance sub-plot because I flubbed something with Ashley. [/sigh] xD Tali by far is my favorite character though, and I just couldn't refuse to help her with her pilgrimage even if the mission was extremely irritating.
Anyways, Ilos is just annoying. Especially with the Geth Primes, they are a pain to deal with. I just hacked all the armatures. Engineer ftw.
I'm thinking on either playing it through again and getting the Level 60 achievement, or playing through as a female Shepard this time. Haven't done it yet. My brother has, and I can tell you the voice actor for the female Shepard is much better at her job than the one for the male Shepard.
