But it's not just the video game market, it's the Steam market. Steam is more than just video game sales, it's also the social component. Steam drives sales because Steam-friends drive sales. Now, those front page ads on Steam don't hurt. But I have a bunch of friends I've made online playing one video game. When most of them started playing Dead Island, I had to get the game too. When they started playing Borderlands, I wanted Borderlands. When they all talk about Skyrim, I want to check out Skyrim.
A few years ago I'll admit I would have just downloaded a game or played an old free one. Now I really enjoy the social aspect and people I'm playing with are hundreds of miles away. I wouldn't be talking with them about games at a coffee shop. It's changed the way I play games.
So when people wonder who'll pick up the games at first, that's not the big deal. The big deal is that it's going to create a market for Steam on linux. On one hand they are already there, land claimed in linux-land, if the market shifts more away from Windows and into linux. Even if it doesn't shift for other reasons, if my friends on Steam are all playing a game that's available on linux I'm more likely to try it out. And if they end up playing a game that is *only* available on linux and linux is free, then I'm definitely going to install linux and play it.
The games here are going to feed Steam and Steam is going to feed the games. And when other companies jump in that market Steam is still going to benefit from it.
