I enjoyed it. While exploration can be a bit tedious (there's a lot of planet to explore), and there were a couple broken or incomplete quests, combat was fun, the characters were interesting, and I liked the main questline. Compare to ME1-3, you're in a tiny slice of the galaxy (no jumpgates to allow instantaneous transport across interstellar space), but I also found the planet exploration to be a lot more DOABLE in MEA than ME1 (driving requires less patience and pixel-bitching), and the galaxy exploration is comparable to ME3.

I liked the "Choose your powers" character creation system. I didn't use much of the combat powers (mostly "Improve the weapons I was already using"), but I wound up having to respec to make who I wanted, and the Charge+Detonate distinction made for some fun combos.
