You also have to look at the fact that the developers that continue to support the MMOs do make expansion packs which sell like made meaning that they do help keep market share up due to all the sales of the expansions.
Also all subscription fees goes to computer companies for new server upgrades, development costs for expansion packs, and fund new title development.
MMOs really dont hurt the market as much as people think. Plus, some MMO players do actually buy other games and play them.
