Well, this was a game I was really waiting for… And (as you may already heard on the internet) it was bittersweet…
First, let’s get the good out of the way:
The game is freaking amazing… it’s probably one of the best games in its genre (and of any genre, to be honest), that gripped me from beginning to end… except for the last 10 minutes, but I’ll go into that in a bit…
The storytelling was the usual Bioware-grade bonanza, with a bit of everything, including some unexpected curve-balls which kept the game interesting!
It was one of the first games where the concept of cooperation as a path to victory didn’t fill me with annoyance, and it really made sense, with tons of difficult choices along the way which made me feel like I was really Sheppard…
I really can’t say anything about the game that hasn’t been said a million times by reviewers and fans all over; it’s a masterpiece of gaming, specially because it makes overlook its faults (the graphics are a bit outdated, the interface a bit clunky sometimes, etc, etc) and pushes you to delve into the galactic war scenario where you’re facing insurmountable odds in name of something larger than yourself… and that’s cool… 
Unfortunately, what would be a 10 out of 10 game is spoiled by the last 10 minutes… the ending is one of the most appalling, badly cooked endings I’ve ever seen, filled with plot-holes and general nonsense that kind of ruins the whole experience… I can’t say more without going into spoilers (and that’s what I’ll do after the break in the post).
Anyway, how do you rate a game like this? A game that made you feel like you were on an epic movie, the game you felt you always wanted to play, a game that you spend 40+ hours enjoying, but at the same time delivered a punch in the stomach in the last 10 minutes that makes you feel like “Mega Shark vs Giant Octopus” was a great coherent movie?
I would be unfair to rate it less that 9/10, but at the same time, the game really made me mad!
My suggestion is that you play it for yourself, even with the pain at the end and come to your own conclusions!
Now, for the spoilers part:
