Spectacular game! Click continue you gotta read this.
Now, let's continue.
Gameplay: 9/10
For me, in gaming, gameplay is the most important part of the game. Mass effect's gameplay is good. If you liked an RPG, action-adventure and third person shooter you shall play this game. The fighting style is great. You can command your squad to cover, move etc etc.
Storyline: 10/10
Storyline is the 2nd most important part of the game for me. But I don't consider it when I'm rating a game with no storyline (OF COURSE).
It's storyline is one of the best I have ever played. It's very interesting. Stop an ancient machine from reviving and destroying the entire galaxy. I mean it's very unique. No game has this kind of storyline. Other storyline contains "KILL THE ONE WHO DESTROYED YOUR LIFE" and it's very common.
When doing the story missions you can also have your romance plot, which is very LOLing.
Graphics: 9/10
I usually don't look at the graphics of the game. If the game has good gameplay, good storyline and not so good graphics, for me, it doesn't mean that the game sucks.
Graphics is awesome in this game. Seeing the galaxy you are living makes you feel relaxing. The other planets seem so realistic. The motion blur's amazing.
Average: 9.5/10
So, if you haven't got the chance playing this game, buy it now, I MEAN NOW!
