Speaking of the end is THE big problem of the game: it is archi sloppy and despite downloading the latest DLC (Extended Cut) we are still frustrated.
The second complaint is the small lie on the influence of the choices made during the trilogy they have zero influence on the end and that's a shame for fans of the first hour.
Small-GUIÑOS secondary personanges winks are present, according to the choices made, but it has no influence on the game except for songs: ballads of Mass Effect 3 can not be done with the characters of the first 2 parts if has no adequate backup.
Beside that you always have a fantastic depth universe, the action scenes are top with some small new features (melee blows, rolls on the side etc ...) and the multiplayer mode that seemed sloppy at first sight is very friendly to use. It is also mandatory to practice to see a few more seconds at the end of the game. It also has the advantage of playing personanges of all species (Asari Quariens ...).
The game is very action oriented, but there is always the possibility of digging the story of each character, to have various dialogues, and this is a great addition to the series.
When one connects the 3 following, which I recommend, it was only one desire: to see the 4! There is still a lot of possibilities: a new trilogy with new hero, a MMORPG ... Etc
