Tribes

Before starting a game, players must choose a tribe out of the current 17 tribes (16 on iOS). Each tribe will heavily affect your gameplay. New tribes will be released over time.

Tribe uniqueness
Each tribe will have at least one or more of these:
 * a unique guardian (guaranteed)
 * a unique secondary guardian (guaranteed) (unlocked by rubies)
 * a unique kind of unit (guaranteed) (unlocked by rubies)
 * one or more free tech
 * one additional unit
 * an attribute which acts as a permanent buff
 * advantages which give them a head start

Each tribe also has their own terrain generation.

Additionally, each tribe has their cosmetics, which include their own theme song, unit, city and terrain appearances.

List of tribes:
There are 3 ways to unlock a tribe, 2 tribes can be unlocked by achievement, 8 tribes can be unlocked by in-app purchase and 3 tribes can be unlocked by rubies.

Bot-controlled tribes
When going up against bots, the player can only encounter opposing tribes which they own themselves. This also means that the max opponent is limited by the amount of tribes owned.

'''Easter egg: there is actually a small chance for the player to encounter a tribe which they do not own. That tribe will be chosen by random, slightly making each playthrough different.'''
