ME3 is still fantastic. The ending may have been a bit confusing or ambiguous. But the game is still great to play. I've enjoyed a lot of games with trout endings, so at least they tried. I guess doing finales are hard. I've seen a lot of books and movies fail at that most pivotal point as well. So its hard to hold it against them when they pretty much nailed everything else. It doesn't ruin the game, and it certainly doesn't ruin the series. It's just ... there. Nothing more
