Gameplay hasn't changed as it was said. The game is still fun, but you have feeling that its still same game as ME
What's bad in this game is combat, stupid/bad AI, repetitive gameplay. All this three factors are important, cause in some moments the game can be very boring and when you see that you can trough enemies and you will not die, you can easily kill them. Common man this game should be harder.
In the end if you played previous two titles than you need to try this one, cause you will not catch the story and you can import saves from previous games
