1. This announcement is just in poor taste. For crying out loud, Forbes is talking about the ending. If they planned on releasing this app...they should have waited. Like...how soon after a funeral should you ask the widow out?
2. You know...I'm not in agreement with the EvilBiowareAndEABusinessandGreedSucks part. Their job is to make money. I'm okay with that. And how does one make money? In theory, you do it by writing well. If this was a novel, would a publishing company have accepted this ending. I can't believe I spent $60 on this. What percentage went to the writing team? Deduct that, and I would have argued a fair price.
3. Seriously, this game has to be Bioware's baby. Why would you drop a baby?
4. If there's one thing I loved about KOTOR, Jade Empire, and Dragon Age, it's how foreshadowing played a huge factor in the ending. Let's face it, finding out you're Reven is still one of the biggest twists ever. There was so much material to work with! How could this ending be so weak when you have so much material to draw from?
Reapers have been vague about their purposes. Plus, it's not like their reliable narrators.
So has TIM, actually.
Dark energy has been hinted at.
As shown with the asari temple, each species have enough dark secrets to fill an ocean.
The point is, a decent fan fiction writer could take that material and work the ending. Heck, a really good one could make a legit excuse to human-turian or human-AI babies at this point.
