Phantasy Star
梦幻之星
Phantasy Star is a science fiction RPG developed by SEGA in 1987 for the Master System. Players control Alis, a young woman seeking revenge on the evil Lashiec, exploring four planets across a sprawling narrative. The game combines dungeon crawling with turn-based combat against various enemies. Players manage a party of characters, each with distinct abilities and magic spells, while collecting equipment and items to improve their chances. The game features a complex magic system with different spell types for offense, defense, and healing. Navigation occurs through top-down exploration in towns and dungeons, with encounters triggering battle sequences. Level progression occurs through combat experience, and the story advances by completing objectives and locating key items. The game's structure involves traveling between planets, solving environmental puzzles, and facing increasingly difficult enemy encounters leading to the final confrontation.
