15 Developers Whose Games Sell Like Hot Cakes Just With A Mere Announcement

VALVE

… Or, at least Valve when, you know, they actually made games. We haven’t seen much from the legendary developers in recent years, but one cannot soon forget classics like Half-Life and Counter Strike, and more recent masterpieces such as Left 4 Dead and Portal. Not only did these games sell very well, they were also all considered to be among the best in their categories, so much so that people have been clamouring for sequels to all of them even so many years later.
