What past freebies I chose to include and not to include were based on my own perceptions of various factors such as demand (how often they get taken), length of time in which they were given away, and other stuff. If anyone has any suggestions about stuff to add/remove, feel free to shoot 'em at me.
Your call of course, but personally I still say Warsow shouldn't be daggered, even if there may be little demand, since the only way to obtain it is through one of these remaining keys from back in the day.
Other than that though, that's a much shorter list than I thought it'd be, 22 out of 56 if I counted right (admittedly, some of those were old, conditional or limited giveaways). One thing that jumped out to me, Stronghold HD is there but AD 2044 isn't, yet they were given away together and I'm quite sure Stronghold would be in much higher demand.
