For me it was in the orginal Mass Effect on Noveria after i finally stopped Benezia, Liara's mom. It took me a couple time and i enjoyed the challenge. I really enjoyed the whole creepy lab in the mountains and the snow. Plus it felt good saving a species from extinction. Because i hoped it would someday comeback in a good way for me in the game instead of the way it did. I also loved the intensity of the final battle on ME2 as i worked to make sure we kicked butt, and didn't lose anyone. I was really thinking at the time that i would be able to use them on 3. Another fun memory for me was the first time i used a Mako and killed a Thresher Maw after it some Alliance scientist were lured to it by some beacon lol. What are some of your fondest memories of the series?
