Only partially on-topic actually, but I feel damn lucky - last week I won a copy of Audiosurf on a Dew contest - and I also won a contest here not much ago, which gave me a coupon I spent on Operation Flashpoint. Considering that I also downloaded one of the free games from GOG.com, and I used the nice offer a few months where I could buy a game and get another one free, I totaled 5 games already (with the 6th coming as free too), paying only 2 - and that's only as far as GOG.com goes.
Besides the luck, I feel like GOG.com is the one building the luck - if they wouldn't do all of these contests, giveaways, offers and everything, I wouldn't have this much stuff - well done guys! You sure think of those who have little money to spend on games :)

With Steam, but I have it from years now and I don't mind using it at all. And by the way yes, it does get boring after some - that is why I didn't buy it when it came out. Now I got it for free, which makes me a happy person :)
