The most talked-about gaming story of March 2026 has nothing to do with a AAA blockbuster. It’s about a small indie studio making a card game sequel that just destroyed the launch-day player numbers of one of the most hyped shooters of the year. Slay the Spire 2 launched into Early Access on March 5, 2026 — and within hours, it had absolutely embarrassed Marathon on Steam. Here’s how it happened.

How Does an Indie Card Game Beat a AAA Shooter?
Slay the Spire 2 has reached over 280k peak player count on Steam, and continues to go strong. The first Slay the Spire only managed to hit 57k peak players almost three months back — making this a massive leap for the sequel. The game directly competed with Marathon on release, and not only does it compete, it crushes Marathon’s player count by over 200k players.
MegaCrit, the developers, also came out and made a sarcastic X post calling Marathon a game by indie developers — a cheeky victory lap that the gaming community absolutely loved. IANS News
The answer to “how?” is actually simple: trust. The roguelike deckbuilder genre has an extraordinarily loyal following, and MegaCrit spent years building goodwill with the original Slay the Spire — actively listening to player feedback, updating the game consistently, and never chasing trends. When the sequel was announced, fans had zero hesitation.
The Bigger Story — Indies Are Dominating 2026
This shows the same pattern from last year, as small indie studios are already starting to dominate the new age of gaming. Most indie studios are the only ones nowadays that actually listen to player feedback — something that was widely followed by every developer back in the day. IANS News
A fun fact is that Slay the Spire 2 has not even released completely, having only entered Early Access — which shows the amount of trust the gaming community places in small indie studios today. IANS News
