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.

What players say

Players see a promising educational sim about nuclear fission that is still very early in development. Many mention bugs with reactor controls and enrichment mechanics, and note the creator has not updated it in months. Enthusiasm for the concept is widespread, but so is the sense that there is not much content yet.
