#5 Dofus - [ PS2 ]
This is also a browser-based game, but it's a turn-based tactical MMO with a colorful, friendly and strongly Japanese-influenced 2D art style. You have 12 different character classes to choose from, over 350 spells, player-versus-player combat, questing, tradecraft professions, guilds -- just about everything you might expect from a standard MMO. Subscriptions can be purchased in increments of one month, up to a year with a 20% discount, average out to a little under seven dollars a month, and they accept PayPal and several other payment options besides credit cards. Winner of the 2006 IGF Audience Award.
