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 low-stress sandbox where you build tourist resorts on procedurally generated islands, balancing construction and economy at your own pace.

What players say

Players are split: many adore it as a nostalgic, modernized take on Holiday Island, but performance problems make late-game unplayable for some, especially past 6000 tourists. The cluster economy system is confusing, tutorials are weak, and multiplayer crashes regularly.
