I'll admit that I stopped looking at reddit for most game content lately (last year or 2) so my opinion might be outdated. But I do remember the new Assassin's Creed getting quite a lot of hate for gross reasons. It becomes oddly political much like many subs for TV shows and movies. Misogyny and racism are rampant.
That said I suppose if good moderators filter the rabble out there's bound to be some good communities. I just find that if you love a game it's usually best to steer well clear of the subreddit for it.
This is key and one of the reasons that ignoring r/gaming and subbing to r/games instead has been standard wisdom since like 2010 when reddit actually had a guide to which frontpage subs to unsub from (r/pics, r/funny, etc.) and which ones to replace them with.
