Please, implement requirement that a gamer must log 10 Steam hours in any game they are recommending before they can recommend that game. Currently, when a new game is released people play the game for .3 hours then submit a review that says something like, "I watched the intro, and this game looks amazing!" Then the reviewer actually plays the game for some time and edits the review. An hour minimum is good for three reasons: It allows for the hype of games to wear off, the current system encourages thoughtless reviews, and an hour requirement would lead to more Steam recommendation credibility.
First, an hour requirement would allow for more post hype reviews. Gamers want certain games to be amazing, and advertisers influence gamers to believe that games are amazing. So, when gamers gets to playing through the first couple of minutes or hours of a game (barring any glaring glitches) they are still in hypemode. Forcing reviewers to get through the hype will help them review games on merits rather than on hype.
Second, the current system encourages quick and thoughtless reviews. Almost every game contains "top" reviews that are silly one liners. These one line reviews rise to the top becasue the reviews open as soon as the game is released and purchased. Reviewers are basically encouraged to get up any kind of comment to get their review to the top. A minimum hour requriement might not elimiate the one liners however, at least the oneliner would be coming from someone who has put in some time on the game. It would also give reviewers 10 hours to think of a oneliner.
Third, a time requirement would give the recommendations system more credibility. Steam has a unique ability to somewhat quality control reviews (without censoring) that it's not taking advantage of. Steam tracks time played in every game. Therefore, everyone who reads a Steam recommendation can be assured that the person has actually put it the time. This is also more fair to developers. It's inherently unfair for a developer to put countless hours into developing and designing a game, the to allow people to recommend or not recommend it after less than an hour playing it.
Now, I realize that Steam hours could include opening the game and leaving it on the menu screen for 10 hours. Or, it could mean opening the game and dealing with 10 hours of bugs and glitches. And, I also realize that making reviewers wait would prevent reviews from warning about buggy games. However, these concerns are not really issues. Noone is going to just open a game for 10 hours and just sit there just to write a review.Generally, patches are put out quickly (notwithstanding BF4), and it's unlikely .3 hour Steam reviewers are disuading people from buying games.
