This was bound to happen eventually. Marketplace that makes money on people buying any stuff not just good stuff and selling sales to publishers needs stuff to have good reviews regardless of its goodness to drive the sales it's justifying its cut of the revenue for.

It's a risky play because a platform where the reviews are high signal drives sales based on that alone. You can only nudge so much before expectations adjust and would-be buyers have to turn to 3rd party reviews which adds friction.

I imagine it's incredibly tempting to heavily moderate reviews instead of letting gamers do what they do and meme like it's a Reddit thread but that kind of thing is actually fairly high signal albeit low seriousness. Silly comments about having 1k hours in the game but not recommending actually does tell you something real about the game.
