So, my main gaming PC died recently, which spurred me to finally sit down and finish Mass Effect: Andromeda on my PS4. I had been warned that the ending was a letdown, especially since it hints at sequels that will almost certainly never happen now. The warnings were right. After the requisite "allies you have gathered" show up, the final boss fight is just "shoot down waves of robots and hack 3 computers" while the Big Badguy spouts the most generic villain lines of all time. I am not exaggerating - they are so cliché it feels like parody. The Big Bad looks extremely stupid too. He's probably the least serious & intimidating Big Bad of all time. He makes Lord Helmet seem like Jon Irenicus.
Anyway, once you hack all 3 computers, he just sort of falls down and dies. You don't even have to fight the Architect he's controlling. Architects are the biggest robots in the game and by far the hardest enemies to fight... but all of them are optional, and the main story is a cakewalk even on the hardest difficulty. The only time I died in the final fight was when the game crashed. Finally, we're treated to a surprisingly short cutscene, after which we get all these emotional ending conversations with the crew, and then "it's off to the next adventure!"... or not. There are hints of an even bigger big-bad out there, and a search for the Quarian Ark - DLC and sequels that we'll have to leave to our imaginations.
There's not much else I can say that I haven't already... It was a lame soft reboot of the Mass Effect universe that didn't try to do anything very new or interesting, but taken on its own, it wasn't THAT bad - not nearly as bad as its critics made it out to be. I don't feel like I totally wasted my time or my ten bucks. Honestly, I enjoyed it quite a bit more than Dragon Age 3 from the main Bioware studio. *shrug* Shame EA killed it so quickly.
EDIT: Oh! I forgot to mention the results of my choices... There weren't many. The allies I gathered showed up, a few characters were different than they might have been (you get to choose the pathfinders of the other races, and who rules Kedara), etc. - but unless I'm mistaken, I don't think anything I did affected the final outcome of the main story. There were hints of dissent in the enemy ranks that made me wonder if I could drop some truth bombs on the Big Bad and talk him down rather than shoot him down (remember how you could talk Saren into killing himself in ME1? great stuff), but those led nowhere. Disappointing.
