Global streaming metrics that allow you to check this week's hottest hits at a glance! We took a look with the data analysis solution ContentFlux.

Today's protagonist is Slay the Spire 2. We analyzed the trends this game is showing on global streaming charts, as it has once again proven itself to be a representative title of the genre by selling 3 million copies during the Early Access phase prior to its official release.

# The textbook of deck-building roguelikes returns with a sequel

Slay the Spire 2 is the official sequel returning seven years after its predecessor, which set the standard for the deck-building roguelike genre. Set in a spire 1,000 years after the events of the previous game, players embark on a journey to build their own unique deck through choices and battles at every moment.

This title harmoniously combines technological advancements and new strategic elements on top of a proven system. By switching the development engine to Godot, character combat motions and card animations have been enhanced, and convenience has also been improved with features such as the ability to draw paths directly on the map and the constant display of boss icons.

In addition, the 'Enchant' system, which grants permanent special abilities to cards, and the 'Quest' system, which provides conditional rewards, have been added, creating a more sophisticated and multi-dimensional deck-building experience compared to the previous game.

In addition, the up to 4-player multiplayer mode, introduced for the first time in the series, expands the experience of the previous game—which was a solitary climb—into the fun of sharing and cooperation, offering a unique enjoyment of discussing strategies and sharing artifacts with friends.

In addition to the previous game's Ironclad, Silent, and Defect, two new characters have been added: the 'Regent,' who manages 'Star' resources, and the 'Necrobinder,' who controls summoned creatures.

However, fatigue caused by streamer mistakes or excessive advice in the chat was also reflected, and the sentiment indicators were evenly divided at 34% positive, 31% neutral, and 34% negative.

Among French viewers, some sarcastically remarked that it was a DLC rather than a sequel due to its similarities to the previous game. On the other hand, users who disagreed argued that it was an official sequel, citing factors such as the engine replacement and the volume of content.
