Crystal Saga

Crystal Saga is a free browser-based MMORPG. It's fairly standard for its genre, relying on the usual five classes (Knight, Rogue, Mage, Priest and Ranger), and not offering many innovations. However, Crystal Saga's strengths begin with its gorgeous 2D fantasy art and silky animation, featuring over-the-top costumes and special effects. And Crystal Saga's “auto-pilot” feature lets players grind through monsters while being AFK, which really takes away a lot of the drudgery common to browser RPGs.

Crystal Saga includes a good PvP system with PK environments on designated servers. Open PvP is only available to level 20+ players. Five PVP states are available: Peace mode won’t allow you to attack anyone; Evil is lets you attack everyone; Justice allows you to attack red-named players. Finally, Party and Guild modes protect your allies from friendly fires.

The quests are the usual go-and-fetch and kill-X-number-of-monsters. The gameplay of Crystal Saga is mostly typical for an MMORPG game but it features a robust pet system. Like players, the pets also engage in combat, level up, evolve, and learn skills, and players can distribute stats for their pet’s growth.
