Mass Effect 3 is 40 hours long, main quest is 15-20 hours

The world’s first review of Mass Effect 3, from German mag Gamestar, claims that the highly anticipated RPG is roughly 40 hours long. Apparently, the main quest itself will take between 15 and 20 hours and includes 90 minutes worth of cut scenes.
Furthermore, the mag goes on to state that the games has a solid ending without “loose ends or cliffhangers”, but it does tease that there’s “an interesting sequence” after the credits end.
Interestingly, the review goes on to talk about the gameplay design and says that level design is “similar to ME2”, but the game “feels very much like ME1”. Frankly, I’m not quite sure what to make of that – having previewed the first 90 minutes, I didn’t pick up on a Mass Effect 1 feeling at all.
However, not everything is fine and dandy: “the low polycount, lack of detail and low texture resolution” means things can be visually up and down. However, Gamestar goes on to say that “the character are well animated and modeled”.
