Mainly be remembered for Mass Effect 2's magnificent achievement, his fascinating scenario (even if the recruit team members and gain their loyalty does not seem so exciting at first sight) and the presence of DLC in the PS3 edition.
Note also significantly improved graphics from the first part, a wheel still effective dialogues and excellent French dubbing (which is rare enough to be reported). Note also decreased RPG aside in favor of the action which should please some gamers and disappoint others.
It is worth mentioning a few things that annoy, namely many glitches and some framerate drops that occur mostly during the exploration phases. These problems are certainly unpleasant but, mostly, without affecting the gameplay.
Digression about trophies. They are all relatively easy to unlock and get the platinum asked to finish the game at least twice: the first time to unlock the maximum level of difficulty and a second time to finish this mode.
Finally, note that the game ends in forty hours, including quests.
