Half-Life 2, Crysis series, Witcher series, Mass Effect series, Elder Scrolls/Fallout (with mods), Tera, CS: GO, Arma 3, Pillars of Eternity; also use [url]www.cdkeys.com[/url] and [url]www.mmoga.com[/url] to buy games. There are a few others but those are the main two I use, and when you can, I suggest trying to get games through GoG over Steam since it is 100% drm free, and Valve needs some competition.
