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

A precise, educational tool that feels like methodically plotting orbital paths through a photorealistic solar system.

What players say

Players see it as the closest thing to a KSP successor, though it leans heavier on simulation than the original. It relies on automated launches and real-world orbital mechanics, which makes it rewarding for experienced players but very challenging for newcomers. Reviews note the tutorial is thin, but the developer is actively updating.
