Amazon has done a pretty good job with Fallout in my opinion, so I'm hopeful that it doesn't turn Mass Effect into Paramounts version of Halo.

They have to balance the limitless time and nuance a video game has to draw in a player and the things a game can do that a TV series just can't. But as long as they can keep the core elements that made the game so popular and turn it into a 12 episode series, it might be great.

Halo (series) lost what made Halo great. Halo should have been about humanity losing a war to a more advanced alien species and a lone super soldier turns the tide. It should have been gritty, violent, bloody, making friends and losing them to war. It should have been Band of Brothers but on sci-fi steroids.

I didn't get very far into the Mass Effect games but I was thinking something like The Expanse meets Lord of the Rings. A hastely put together motley crew of aliens traveling the universe trying to figure out why these worlds are being attacked and finding a much larger universe ending mystery.
