Good game, could have been better though. The ending was sudden, and continuous play would have been great.
TEASER: Near the end of the game, you have to choose on who to send to battle in hopes that he/she will keep the enemy away enough for you guys to escape and the nuke to explode taking down the arch nemesis down with it. I chose the Ashley rather than Kaidan, since she had more chemistry with Commander Sheppard. If you choose Ashley, you get some sexual pleasure after the mission while on the ship. If you pick Kaidan, well I'm not sure what happens then since I doubt homosexually was influenced in this game.
To continue with my review, I skipped the secondary assignments not know how sudden the ending was. (I won't say what happens) The game ends, and when you play again you are back to where you last saved before the last mission. Problem is that you can't go back to explore the rest of the planets unless you do it early on in the game.
Overall, great game. If it were something like Oblivion where you can keep playing, exploring planets, discovering rare minerals, pwning random aliens, it would be an amazing game, but since none of that was implemented it was demoted a number. Believe it or not, this game is addictive. I couldn't stop playing it with all the suspense, like when Wrex gets killed by a good guy. (it was about 3AM when I experienced) I couldn't wait to see what would happen next so I kept on playing until around 9AM (where I fell asleep on the computer desk and died a couple dozen times...)
