Blue Archive, originally a mobile exclusive, recently launched on Steam with over 20,000 concurrent players and 10,000 reviews.
The developer incentivized players to leave reviews on Steam, a move against Steamworks rules. An in-game event promised rewards for hitting 10,000 reviews.
The event has since been removed, but the review count exceeded the set goal. Blue Archive is now under scrutiny for potentially breaking Steam rules.
Steamworks guidelines prohibit artificial review manipulation and soliciting reviews for rewards, which the alleged Blue Archive event seems to have violated.
