Rock Band 4 has been out for a few weeks, and a couple of suspicious five-star reviews on Amazon were caught by Reddit users.

Harmonix had to clarify the situation, which is why they released a letter admitting the reviews were from their employees, and ordered those who posted to identify themselves as Harmonix staff or delete the review entirely.

"Harmonix has clarified its internal policy about posting reviews of our own products on retail sites, and we've asked that existing reviews be edited to identify Harmonix employees or be removed entirely. While we believe the reviews posted by a few employees were sincere and without ill intentions, as a studio we don’t believe these are appropriate actions. We appreciate the feedback from the community, and take our relationship with our fans seriously."

Some of them were deleted, others were edited to include the writer's staff position, and here is Harmonix's Project Manager Matthew Nordhaus edit.

"I added this review half in jest (as you might be able to tell from the tone of the original). In hindsight, it's probably important that I note that I worked on the game and work for Harmonix. That being said, I'm confident that if I didn't I would still give the game five stars. It's a beautiful, peaceful, cooperative game, rare enough already in today's landscape, that I can play with my wife and kids. Music discovery, playing with your family and friends, and cooperation make Rock Bandmy favorite."

I didn't play Rock Band 4 personally, but from the reviews I have seen, the game doesn't need those extra positive reviews.
