All non BTA games on one key. I hate that shit, I only want one of the games and I'd just give the rest away if they were on separate keys. Seems like most of the time it's all one key nowadays though.
Are you seriously complaining that you can't give away games that you got for $1? I understand it's annoying when you already own some of the games, but it's so cheap. If others want it, just have them spend the $1, or send them a gift if they can't.
