I do not have any access to truly insider information from Wizards of the Coast or Hasbro.
Hasbro Financials (this includes transcripts from Investor Day, Accounting and Financial Statements, Annual Investor Report).
Based on those numbers we would have revenues of 250-500M (Million) dollars this year.
Alternatively Hasbro reports 12M active magic players (including digital). Assuming each only spends 30$ per year on average. Then revenues are $360M. Hasbro’s revenues from “Games” is $1.2 Billion. It has stated that Magic is the biggest brand in the portfolio. Thus the the estimates seem reasonable.
*EDIT 11/20: The Hasbro 2012 report states there are 3.3M players currently. Despite their being an NBC article which quotes 12M as of 2013. The only official Hasbro source which uses the 12M number is a few years old, so I will be editing the range of players.
However there is little evidence that Hasbro makes many decisions re: the Magic the Gathering brand. I have read (in a statement by Aaron Forsythe I believe) that Hasbro has little input on the decisions to manage Wizards of the Coast properties. Sean McGowan (an analyst at Needham & Co.) says “The Best thing [Hasbro] did was leave [Magic] alone for several years.” when discussing the explosion in Magic’s popularity.
I remember seeing somewhere that MODO is equivalent to North American revenues for Magic, was also equal to about 30-50% of overall revenues. Assuming this is true (it was according to Worth in 2007), and using the base number of 360M revenues overall, we estimate MODO has a revenue of 144M.
Assuming the average player spends $100 a year (which seems reasonable), then there are 1.4M people who touch MODO in a given year.
According to Reddit other sources place MODO playerbase at 500,000.
According to the Linked In of Vice President of Digital Technology he is “Responsible for managing the technology development and operations for the Magic Online, free-to-play digital objects business, Duels of the Planeswalkers game title (XBLA, Steam, iTunes, Android Market) and the subscription D&Di digital experience.”
Are WotC software developers underpaid?
Also note that Hasbro is routinely voted one of the best places to work in the United States (via Fortune Magazine). However most of the benefits are perks and not direct compensation.
Hasbro already pays EA studios to develop games for 8 of its various brands. It has also acquired a majority stake in Backflip Studios (a mobile game developer). Duels of the Planeswalkers is developed by a third party and the original version of MODO was developed by a professional studio. Current versions are made inhouse.
Wizards is currently hiring Senior Magic Developers/Testers/Technology Project managers to work on MODO (as of Nov 5/2013).
