Planet Catalog & Ratings

Planets are memorable because their names always mean the same thing. Every world maps to a fixed identity, a quality tier, and a set of production multipliers.

Rating scale

Instead of dry numbers, planets use a player-facing S-tier scale with a friendly label. Higher tiers mean better production and more buildable land.

Tier	Label	Tier	Label	Tier	Label
S+++	Mythic	A+	Rich	C+	Weak
S++	Legendary	A	Strong	C	Poor
S+	Elite	A-	Favorable	C-	Harsh
S	Excellent	B+	Good	D+	Barren
S-	Superb	B	Average	D	Severe
		B-	Fair	D-	Brutal
				F	Barely Useful

Buildable land

A planet's slot count determines how many Factories and Tech Labs fit on it. Slot counts range from 4 to 10.

Slots	Rating
1–3	Low
4–6	Normal
7–9	High
10+	Massive

High-value icons

Small icons flag a world's standout strengths (limited to the top one or two to avoid clutter):

👑 Homeworld
🪙↑ High gold potential
🚀↑ High shipbuilding potential
🧪↑ High tech potential
🏗↑ High buildable land
⭐ High overall quality

Named planet catalog

The multipliers scale a planet's gold and ship output; Tech affinity nudges research. These are the fixed identities every named world carries.

Generated names for large maps

When a map needs more worlds than the catalog holds, names are generated by tier, so the profile always matches the name. A legendary-sounding name never lands on a poor planet.
