It used to be that there was only a very narrow market for games, but now there is casual, hard core, mobile, tablet and console, desktop, MMO's, indy, web. But to offset that the market is also much bigger and more inclusive. There are people that now pay for video games that would never have bought a Nintendo or an Xbox. If you want to make money in video games you have to find a niche and give that audience quality versions of what they want.
