Perimeter: Emperor's Testament is a real-time strategy game that strongly emphasizes problem-solving, strategic thinking, and critical thinking through its complex gameplay and terraforming mechanics. Players will also engage their spatial awareness, memory, and adaptive challenge skills. The game's narrative requires reading and comprehension. While not a core mechanic, the game demands hand-eye coordination, fine motor skills, and reaction time due to its fast-paced nature.

The primary risks in Perimeter: Emperor's Testament stem from its content. The game features a moderate level of violence inherent in a strategy game focused on warfare between factions. There is also a mild element of fear/horror present in the descriptions of the 'Psychosphere' and the 'Scourge'. The game's narrative, with its competing ideologies and factions, could be interpreted as having a mild level of propaganda, although it does not appear to be overtly manipulative.
