Goldcool's Magic World Online, a fairly straightforward fantasy MMO, offers the usual mix of monsters and quests, along with several standout features. These include a built-in legal bot that allows the player to automate some tasks, weapons that grow with use, the ability to change classes, and moving castles that, once owned, allow for large-scale guild battles within.
Friends can play together while they run integrated video chat, making the social aspects a highlight. MWO has an optional item shop for further customization.
