I was extremely surprised to find a few reviews saying that this game is short - these people obviously only did the vital missions, most people who actually played the whole game got 30-40 hours play time, I got 34 hours out of it on my first playthrough and I only completed it 80%. And so much for replay value - there are many different endings in the fantastic story line and you have to play it at least 3 times through to get the full 1000 points.
This is definitely the biggest map on the 360, you can explore the whole milky way and solar systems are added when you complete assignments and story missions.
The music is excellent and fits in perfectly, a wonderful addition to beautifully real-looking graphics.
Choose your squad, weapons, outfits and upgrades as you lead your crew on a mission to save humanity from a spectre gone rogue, Saren.
You make real decisions that impact your game through the use of the conversation wheel which I love. You can even develop relationships with the other characters which really draw you into the game world and makes you really care about what happens to all of your crew, thus making the decisions you have to make all the more difficult!
In the making for 4 years, this game has definitely delivered, and I can't wait for the others in this incredible trilogy. Prepare to be hooked.
