my main problem with the ending
is it's just like all deus ex endings (all 3) Despite that being my favorite franchise, and lestatdark liking them, I think all deus ex endings aren't executed very well, though some of the ideas are intriguing. This is what I feel about ME3. The games gives you choices throughout the it that don't effect the outcome at the end. Which just seems silly beings there's events that occur that are more complex throughout the game in each series.
Now I don't think the endings aweful, abysmal, etc. Because no matter what they did, people would be pissed I think.
