There’s a game that’s blowing up on Steam right now, but it’s not a big-budget blockbuster. It’s Fire Pro Wrestling World, an old-school-style wrestling game that’s still in beta.

Fire Pro Wrestling is a wrestling game series that saw its start in 1989 on the TurboGrafx-16. Since then, there have been dozens of iterations of Fire Pro Wrestling Games across more than a dozen different platforms. The series has developed quite a fandom thanks to the games’ use of characters that are almost the same as real wrestlers and their superior combat systems compared to other wrestling games.

The latest game in the series, Fire Pro Wrestling World, just released on Steam Early Access this week and quickly became one of the top-selling games on Steam for the past couple of days despite its beta status.

Fire Pro Wrestling World sticks to what the series does best with its old-school vibe, true-to-life moves, emphasis on grappling and timing, and huge cast of characters that are very similar to current and past pro wrestlers from around the world.

What makes World particularly special is its robust customization options. With over 1,000 moves to choose from and tons of customization options, players can create pretty much anything they imagine.

Here’s a Laser Time video showing a taste of the kinds of characters some people have already created in Fire Pro Wrestling World:

The last original Fire Pro Wrestling game (a.k.a. games that weren’t rereleases of older Fire Pro Wrestling games) came out in Japan in 2005 and the U.S. in 2007, so it’s been a long wait for fans of the series.
