Seeking Alpha is a website devoted to investing and financial matters. (It's name is from the alpha coefficient in finance which can be understood as return on invested capital.) In a recent article, Bruce Everiss looks at Apple's iTunes and Nokia's phone-based music subscription model and suggests that subscriptions might be appealing to gamers.
You can see quite clearly here that this is a business model that can be applied to gaming. Payment of a subscription which covers all your gaming requirements. Instead of buying individual games. This is a formula that John Riccitiello has alluded to in the past. Now we don’t need it for consoles but it would be really sweet for the pirate riddled mess that is PC gaming. Maybe as an evolution of Steam, or possibly as a totally new service. And as broadband bandwidths increase it would be perfect for server based gaming.
