I just had a look at the site myself having read the GP comment. The layout felt reasonably unambiguous and accessible to me personally, although everyone's different - but then when I clicked a game and wanted to go back to look at another one, I noticed that my browser's back button was disabled!

Sure enough, a global search showed that you're using history.replace() to change the URL path. I can totally appreciate the likely trepidation about the work required to correctly juggle the JS history stack, but... it's very disorientating to see the back button greyed out :)

I know it'll get fixed eventually, but I crashed into it within 6 seconds. ¯\_(ツ)_/¯

Also, it would be kind of cool to be able to watch active games, but the current UI doesn't really surface activity in any way. Adding this would naturally attract ebb and flow and interesting oscillatory behavior (with lots of people randomly joining and leaving) and whatnot, but it would also allow for actual large-scale spectation, and the general appearance of a site that's a Destination™ and a flurry of activity.

(While probably obvious, I've just thought that recency (what's being played right now), activity (what's attracting the most chat and the most frequent/periodic/consistent movement), and volume (what has the most eyes on it) would all play a role in ranking.)
