As per title, decided to have a quick look at the daily sale on GameFly at the moment, among all the regional restricted games, I saw these two, both are $0.99 and register on Steam
Serious Sam HD: The First Encounter
Serious Sam HD: The Second Encounter
P.S. GameFly PC downloads used to be Direct2Drive
I'm not going to play either of these damn games again, but for $1 to add to my steam library.. Damn you steam!
