Picture four heroes standing across from a dragon. Each party member has three actions queued. The mage goes first, debuffs the dragon's fire resistance, then the warrior uses a fire sword for double damage. That is the turn-based RPG at its best: a tactics puzzle wrapped in a story.

Summer Engine helps you build the battle system, party management, ability trees, and world structure through conversation. You define the story beats, the enemy rosters, and the fantasy. The AI handles the combat framework and stat scaffolding.

The best turn-based RPGs reward learning the systems deeply. Every boss encounter should feel like a test of everything the player has learned about how the party works. Building those encounters is the creative work. The systems support it.
