No.
I'll also go one step farther and say that all user reviews are useless, in part because of morons writing reviews that have absolutely nothing to do with a game's merits.
Another one...
I'll just make a quick post from the things I posted in another thread.
User reviews are invaluable when trying to figure out the quality of the port, or when trying to figure out if a small unknown indie game is worth looking at.
I would never have tried Heartbeat if the user reviews weren't amazing. I wouldn't have tried Monolith, Bytepath, Linelight, or a bunch of other games on
https://steam250.com/hidden_gems if it wasn't for the glowing user reviews either. I ended up enjoying all of them. My top games of 2018 list even had multiple games which don't even have enough reviews for a score on MC and would need to rely on user reviews. All PC exclusive indies. For example:
BallisticNG - 0 reviews
ZeroRanger - 2 reviews
EXAPUNKS - 1 review
As
BernardoOne points out, Parkitect also has similar numbers, as do a lot PC exclusive indies. It's fairly normal in this space. EXAPUNKS is even fairly well known and by an established developer in Zachtronics! The mainstream gaming media doesn't really care about PC representation. User reviews are needed to pick up the slack and get good word out to people.
For other example. This guy (in german) goes through and writes reviews based on his work figuring out what games track what user data, where that data gets sent to, and what consumers can do to block it:
https://steamcommunity.com/id/pen-chan/recommended/. This is data which would be pretty much unavailable otherwise in an easy to find important place, especially since no mainstream gaming media would ever cover something like that. What would otherwise be lost in the mess of gaming forums and Twitter gets put right on the games page, where consumers can read it and make an informed decision. His reviews are often really highly rated, and on Steam the highly rated reviews get pushed to the top.
People currently interested in Ace Combat 7 - HOTAS isn't supported, it isn't mentioned anywhere on the Steam page, yet the user reviews are filled with people commenting on it. If someone wanted to buy it, they would get information they wouldn't have otherwise, again showing how useful it is. You could argue "well you should research before you buy anyway!", and sure, but user reviews are already one of the best and most convenient ways of researching, why get rid of it for an inferior solution?
As
Stone Ocean mentions, Dark Void Zero is still available on the Steam store. The page does not mention anything about how if you'll buy it, the game will straight up not work because of broken Securom. The page doesn't mention this anywhere. You know where it is mentioned though?
The highest voted user review. Right on the games page where any interested customer would be likely to see it. Anyone who says user reviews are pointless doesn't know what they are talking about.
