User blog comment:Turk0047/What is the average time to beat this game in?/@comment-1074875-20100210111452

It depends on whether you complete all missions and assignments of the game. You could do only the plot related missions to get to the Omega Relay without a full squad and loyalty.

Other then that, you have the difficulty settings, play-style, etc. I for example usually finish games at twice the average time - it's possible that there is someone who can do the opposite.
