The worst of the worst. Steam users will relentlessly downvote your review into oblivion if you so much as criticize their favorite game, but will upvote inside jokes and other garbage "reviews" that don't help people out at all. If you base your purchases off Steam reviews you may just be a retard
If you decide not to recommend a game, you must provide a 10 paragraph essay about why you don't like the game and you have to still kiss the game's ass the whole time and downplay any frustrations you might have, lest you succumb to the wrath of the Steam hordes. This strict mob mentality is not applied if you decide to recommend a game, then you can write damn near anything and get upvotes.
