I'm guessing most of you must navigate the threads by going to active threads/latest/currently trending, so if the 'gamers' are pretty active then you are going to get mostly games threads at the top of the list.
I've never had an issue, as I always go straight to 'Forums', and simply choose one the 'Forum Topics' which I like to look at regularly ... usually 'AIBU', 'Ask a Gran' and 'Grandparenting'. I've never seen any games threads on any of those. Only recently have I looked at the 'Chat' thread, and participated in a little game for the first time, which I found quite entertaining.
I've also noticed that there already is a 'Games' thread, so I guess the posters who start games threads should try to remember to post them there, instead of posting them on other threads where people like to have discussions. I don't understand why those at GNHQ can't simply divert any games threads to the 'Games Forum' ...
