I guess there’s the issue right there: If I can do many things well, and I’m easily distracted, how do I choose a focus?

What are your interests? Do you want to go beyond halo? I think that you can explore a variety of things so long as it fits under the concept of the website as a whole. A halo site may not do so well at discussing Battlefield. But a gaming website could have separate categories for each game you are interested in.

Similarly, a halo site could include graphics/videos/t-shirt designs etc which have some kind of connection to halo. And the occasional peppering of astronomy makes for a good read on a halo site. But if you want to rank for astronomy then a separate site for that would be better.

Ultimately, if your goal is to draw traffic, I think that your best bet is to have a separate site for each major interest (one for halo, one for Battlefield, one for Destiny, etc) simply because by putting the name of the game in the website’s name gives you an instant SEO advantage over other sites which do not.

However, getting traffic is different than encouraging participation. And multiple sites is more difficult to keep a handle on. I think that for the primary purpose of building participation it may be better to have a gaming site with categories by game.
