The 3D catalog: game boxes on wooden shelves, with the cat sitting at the counter next to its greeting.

The catalog in 3D

The same catalog has a room you can walk around in. The cat behind the counter is the AI Catbot, and they pick real games from it when you tell them what you feel like playing. Nothing is for sale, here or in there. Go in from here and this game is already out on the counter, with more like it waiting on the shelf next to it.

How it feels

You manage a shadowy intelligence division in a tense, turn-based global cold war where every decision carries weight and the future of superpowers hangs in the balance.

What players say

Players compare Sigma Theory to a board game with short, tense runs. Many praise the espionage loop and endgame pressure, but frustration is common over unclear outcomes, heavy randomness, and a barebone tutorial. Opinions split on whether the AI feels fair or too fast.
