Yeah Wrex! Definitely one of my favorite characters. As far as achievements go, it's much easier to get them in the next two games, since there is less of an open-world set up to the game. Combat gets WAY better in the next two games, and so does the character development. Tali and Garrus are sort of your core crew members through the whole series, but all the main characters from the first game get appearances in the second and third games (if not both of them).
Don't even get me started on the ending! I still believe that the series is one of the best ever, but THAT ENDING!!!
The extended cut add-on
sort of fixed it, but it's still not what I would've expected from such a stellar trilogy. They were definitely either rushed into not completing the ending, or they just wanted to try to be really "artistic" and "different" with it, and messed it up entirely.
