> Most games will be woefully outdated after a decade

I don't think the age of a game has much to do with it, especially for games which are receiving ongoing support from the developer.

DotA 2 is 10 years old -- or closer to 20 years if you count the Warcraft 3 map it evolved from -- and still actively played.

CS:GO is 11 years old, and is also an evolution of a Half-Life mod from 2000.

League of Legends is 14 years old.
