Disappointing, but a hell of a ride.
Starts up with a gripping prologue (Like all Bioware games) but then manages to get less interesting throughout the game. I would of put "Positive role model", but compared to the other games in the trilogy, there are barely any dialogue choices to be made.
Overall: Barely any choices in the last two games had consequences, terrible plot (TIM: "We brought you back to life, now we want you dead.", no interesting scenery or exploration, lack of dialogue wheel, lack of actual side missions (compared to ME1 & 2 planet scanning anomalies), no character development and lastly, didn't even feel like a Mass Effect game.
The game really should of been delayed until 2013, instead of releasing it incomplete and receiving tons of negative feedback because of it. Not as good as ME1 or ME2 but nonetheless a good experience, wouldn't call it GOTY, yet wouldn't call it a terrible game.
