Portal started as a tech demo. 10 people worked full-time for 2 years and 4 month.

It's pretty close to an indy game. But if HL2 development is included then it's definitely not indy.

I cheated and used the recruitment mod and trained and equipped the hell out of a squad and went on a grand tour hitting every major settlement and freeing the slaves, because I wanted to better the world.

And then I put holy nation paladins in the peeler for my own amusement. That reminds me I think I still have Longen in a cage somewhere.
