What you need to know Sea of Thieves is an open-world pirate game from Rare.

Forza Horizon 4 is an open-world racing game from Playground Games.

Sea of Thieves recently crossed 8.4 million players on Xbox One and PC.

Forza Horizon 4 recently crossed the 10-million mark on the same systems.

Sea of Thieves is the latest game from developer Rare. The team has worked on titles like Banjo-Kazooie and Perfect Dark in the past, so a pirate simulator is quite a radical departure. While the title launched as a barebones experience, the team has since managed to turn it around by adding mechanics like fishing, cooking, and even a single-player campaign.

In April, the developer released the "Anniversary Update" for the game. Since then, the number of players has spiked. According to the team, the title now numbers over 8.4 million players. This information was revealed during an Inside Xbox show a few days ago. If you haven't played the game yet, be sure to jump in because it's quite good.

This information was first spotted by Twitter user "@emiel1981" while watching a Forza Horizon 4 livestream on Mixer.

Forza Horizon 4 garnered stellar reviews at launch and has one of the highest scores on Metacritic. That contributes to the game's continued popularity. The racing simulator is also getting a Lego expansion soon, so that should draw even more players in. It's great to see that Forza Horizon 4 and Sea of Thieves are doing so well.
