Bandai Namco released Dragon Ball FighterZ a little over two weeks ago, and the game quickly became the most-played fighting game in Steam's history, with 44.3k active players at launch. Since then, however, the player base has quickly plummeted, dropping by 80% in two weeks, which is a pretty massive swing.
GitHyp reports that the concurrent player count for the last weekend was just over 9000 on Steam, which maths out to approximately an 80% loss (it's technically 79.684 and change). In comparison, the publisher's previous fighter and prior Steam record holder, Tekken 7 — which brought in 18k players on Steam at launch — lost the same percentage of players over the course of two months.
Part of this is the limited shelf-life of fighters, but the extremely short life of Dragon Ball FighterZ comes as a bit of a surprise. The game was well reviewed overall and even made it into the EVO 2018 lineup with producer Tomoko Hiroki entering the ring as a competitor. DBFZ was also one of Bandai Namco's biggest sellers for the third quarter, bringing in 65.4 million yen.
We can hope the tournament buzz and DLC plans for the game will bring back some fans, considering how both Tekken 7 and Street Fighter V have done post-launch, that hope seems a bit far-fetched. Of course, these numbers only reflect the current Steam users for the game, and do not account for the game's popularity on console.
