Imagine a person who wants to work on large volumes of search data. How many opportunities in life does such person have? Not many: work for Google, work for Bing, work for Ask.com, and that's it. By narrowing down your scope of interest you're making it a lot harder or even impossible to make money beyond wages. Another point to consider is that you will do much better if you focus on a demographic instead of technology (like most geeks do). Ask yourself - do I want to make teenage gamers happy? Well, how about elderly gamers? What kind of games could they want to play? Something from their childhood? Something to play with grand-children? What kind of problems do they face - font size? Pace? Demographics > technology.
