I have finally officially fallen in love with Steam. I've been looking for an excuse to fall in love with my PC setup again and Steam is the perfect reason for me. A few questions for you Steam pros, if you please:
When you choose to "Add a non-Steam game" to your games list within Steam, does it track the time you play them and includ it in your account stats?
Does it count towards achievements or are those reserved for games you purchase through steam?
How does it handle games purchased at retail but that are also available from Steam?
