Jim is spot-on, I mean, look at the Polygon front page. One article about an actual video game, two if you count the Elder Scrolls mini game.
Pretty much every website that was once about videogames has become some kind of generalized outlet for "geek" stuff, and usually just mainstream geek stuff like GoT and Marvel movies.
There's a lot of room for these sites to get out of the daily news cycle of videogame reporting and do things like studies on retro games, longer pieces on companies, maybe a look back at the GoT Telltale game and tabletop RPG if they really want to tie in with the current zeitgeist. But that takes more effort and isn't as easy as churning out an 800-word quick hit piece on reactions about the show's finale, so this is what we get.
