GOG.com is running some nice discount for their games. Unlike Steam or those platform, you do not need internet connections once you install the game. While I am more interested in the Star Wars and those old Lucasfilm classic games, there are other choices that might fit you. Take a look of their front page and see anything interest you.
My interest are :
Star Wars Blaster Bundle - $28.72 (X-Wing vs TIE fighters and those 7 other games)
Star Wars Saber Bundle - $22.44 (KOTOR, KOTOR 2, Republic commando, etc)
Lucasfilm Bundle - $16.90 (LOOM, MonkeyIsland, Indiana Jones, etc)
If you purchase something through a post on our site, Slickdeals may get a small share of the sale.
