Phantasy Star Online

Phantasy Star Online is a multiplayer online action RPG developed by Sonic Team and published by Sega for the Dreamcast. It was released in 2001 and later ported to other platforms. Players create a character from nine possible class-proportions templates, pick a name (which determines a color badge), and descend to the surface of the planet Ragol to investigate the disappearance of the Pioneer 1 colony. The game features real-time combat, three distinct classes with unique weapon specializations, and a customizable companion called a MAG that boosts stats and can unleash powerful photon blasts. Up to four players can team up online to tackle quests, though the game also supports a full offline single-player campaign. The visual style is a clean, colorful anime-inspired sci-fi, and the soundtrack features atmospheric electronic compositions. PSO is widely regarded as a landmark title in console online gaming, introducing many players to the concept of cooperative dungeon crawling with friends over the internet.
