Some people might disagree that Mass Effect 2 is the best in the series, because it stripped back so much of the first game, but it made for a much more streamlined experience.
Yeah, you might miss the feeling of wonder that came from Mako exploration, but at least you're not going to be spending your night trying to jump up a vertical cliff face.
What makes Mass Effect 2 special is the premise: you need to build a squad for what's considered to be a suicide mission near the end of the game. Your decisions will determine who lives and who dies.
It's rare the stakes are so high in a videogame, and that's what makes it great. Anyway, head over to Origin and get it ed while you can, on the house.
Keep in mind that there's no gamepad , so you'll be playing with mouse and keyboard unless you're willing to mod.
