Along with sweet sweet deals like System Shock 2 for $1.49 or the enhanced edition of the Witcher 2 for 2.99$.
Going to Good Old Games now you can get Battle Realms +Winter Of The Wolf for free. However buying games gets you more free games.
The first free game comes after spending $1 and is Sim City 2000 Special Edition. The second one is S.T.A.L.K.E.R. clear sky and will be free after you spend 20$. And lastly at 50$ you get XENONAUTS.
So just before the steam sales I would consider going to GOG to get some amazing games because I think GOG does way better sales. So go here and check it out: https://www.gog.com/
