Pets & collection

Create a Roblox pets or collection game with AI

A collection game runs on a simple desire: to complete. Pets add a visible companion that follows the player — that is what gets shown, and what gets compared.

What makes a good pets & collection

The companion is the status

A pet that floats next to the player is a badge everyone sees. Rare pets must look rare from a distance.

Odds are displayed

Show the probability of each rarity on the egg. It is both fairer and, on Roblox, expected.

Trading needs a ceremony

Both players see the same offer, both confirm, the server swaps atomically. Anything less produces scams and support requests.

The systems to write

  • Eggs and rolls — Server-side rolls with displayed odds and pity where wanted.
  • Collection — An index of everything discovered, per player.
  • Companion — Equipped pets that follow the player and grant bonuses.
  • Trading — A two-sided confirmation and an atomic server swap.

Common pitfalls

Odds are not displayed.

Show them on the egg. Hidden odds are both unfair and against expectations of the platform.

A trade can be cancelled on one side after confirmation.

The server locks both inventories, checks both confirmations, then swaps in one step.

What Nemesis builds for a pets & collection

Nemesis builds the hatching area and zones, writes server-side eggs with displayed odds, the collection index, the following companion with its bonuses, and — if you want it — a two-sided trade. A short playtest then walks the character to the eggs, reads the logs and fixes console errors. Trading needs two players, so that test is yours.

Visual direction enforced by the quality check: balanced exposure and contrast, nothing washed out.

Frequently asked

How many pets for a launch?

Twenty to forty across four rarities. It gives the collection depth and keeps every model consistent with the game's style.

Can pets be generated as 3D models?

Nemesis can produce a few signature models on a small budget per project, and builds the rest with the shape engine so the collection stays consistent. Twenty unique generated models would cost more and look less coherent.
