Yeah my first reaction when I see an interesting new game on Steam or elsewhere is to search r/games (NOT r/gaming lol) for the game's name and look around at what people have to say about it. They're often very detailed and honest.
It's probably a good thing that reddit seems to have been too incompetent to enshittify their site completely yet. There's lots of it that has been, but there's still plenty of very good discussion there if you know where to look.
I find reddit to be so hypercritical of everything to the point of it not being useful anymore. A very good 9/10 game will get so much criticism you'd think it's the worst game to be released in a decade.
I'll admit that I stopped looking at reddit for most game content lately (last year or 2) so my opinion might be outdated.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.
