What is Grim Siege?

+you want ranked online duels or adjustable AI opponents
+you like combining card effects to disrupt enemy plans

Not for you if...

Does Grim Siege use AI-generated content?

Yes. The developers disclose AI-generated content on the game's Steam page:

Grim Siege was created by a solo developer with the support of friends and acquaintances. Generative AI tools were used as a supporting tool to speed up the development of some assets — including card art and UI elements. The game does not use generative AI in real time during gameplay — all content is created and finalized during development.

The statement mentions: Art

Self-reported by the developer under Steam rules: it covers AI content that ships in the game, not tools used to make it. Steam page checked on Oct 30, 2026. How to filter AI games on Steam
