There have been quite a few releases for magic-themed game Wizard101 of late as well as the preview of the first expansion. Enough so that WhatTheyPlay has posted an overview aimed at parents to explain the basis of the game and what they can expect if their kids play it.
In a nutshell, Wizard101 is a world where players are students of magic. Combat relies on a trading card system and is turn-based. No one ever "dies" in the game. It's free to play in much the same way that Runescape is - meaning that many areas and quests are only available to paid accounts. The options are numerous in terms of membership levels depending upon what the players (or their parents) want to be able to do. For those parents worried about the community, they do discuss the limitations on communication and the average age of players (about 12). Then again, with family plan pricing available, parents could join their kids in the game and find out for themselves what it's all about.
