Ever wondered how the game Portal became one of the best titles ever released by Valve from being a mere school project led by 5 students? It was “Narbacular Drop” at first, a game that includes portals with teeth, using its own engine. After gaining attention of Gabe Newell, that school project became something much more. I should probably cut the small talk and let us watch the video released by Valve News Network: To be sincere, I did not know that GlaDos was a Hopper mine cube. And to be clear: After seeing its first stages of development, I loved Portal and its developers more than ever. Thanks for the experience guys&gals.
