"Don't be scared off by the low rating. It has nothing to do with the game itself, and more to do with people complaining about the DRM that was used (SecuROM). If that bothers you, Steam sells a SecuROM-free edition. None of the other Mass Effect games apart from the first installment come with SecuROM."
"The Orange Box is on the list because it includes Half-Life 2 and the Half-Life 2 Episode pack, and it is the cheapest and most cost effective means of getting them as well. The Orange Box also includes a couple games produced by the same developer that are not sci-fi."
