Sometimes technology is often an unsung hero in game development. The visual art or game design often tends to get a lot of coverage because it's easier to show screenshots or talk about gameplay than to really show off tech.
BitRaider provides an interesting bit of tech that allows you to start playing a game before it has all been downloaded. It's a pretty neat bit of tech, something that many game developers have discussed over the years. I interviewed Royal O'Brien, the co-founder of BitRaider, to get his perspective on the technological and business sides of the game industry.
