honestly, i loving loathe this game because of the endings.
I was disappointed with the ending like pretty much everyone else, but I wouldn't go so far as loathing the entire game simply because of the bad ending.
The game up until the ending made me feel the weight of my actions. As I was progressing through the game, building my alliances and making tough decisions, the decisions were always on my mind and I definitely had doubts about the consequences. Throughout the game I was constantly asking myself, "was that the right decision?", "what kind of person do these decisions make me?", etc. The game stirred a lot of emotions and really made you feel like you were in a desperate race to save not only Earth, but the entire galaxy.
It's just unfortunate that it was wrapped up so poorly...
