Petrell: Only problem with them appearing at steam is that you can't play them without getting steam mallware on your computer anymore :( so I do hope this does not become common practice. They should offer non-steam version as well.
TheCheese33: Steam is NOT malware. It brings no harm to your computer, and it is a great way to get games.
It does however contain product activation, product deactivation, "phoning home", and other behaviors of DRM schemes. I personally would prefer that free games not be Steam exclusives. I have no interest in America's Army, but I'm not a Steam user and never will be.
This is personal decision however. I have no interest in a discussion about Steam. It's been covered in enough threads here before. There are those of us who choose not to participate, and those of us who do.
