The first Portal…
Portal has been a resounding success for Valve. It has shown how a small game with a simple concept can be a lot of fun, but not many people realise that the actual concept is not new. In fact, there was a degree project by a Jeep Barnett at DigiPen called Narbacular Drop in which the concept of jumping through dynamic portals to bypass obstacles was first developed. This was back in 2004, the game went on to win a variety of awards at the time and still has a fan following.
So… why didn’t Valve get sued by the original creators? Simple, they employed them. Valve were so impressed by Jeep Barnett and his project that they employed his and some of the original team. Later on, they became the team leaders of the Portal project, developing the idea they came up and crafting it from the fairly crude “Princess no-knees” to the highly polished product most of us played last year.
A bit of trivia for those interested. 🙂
