While I agree with all that, WoW’s a special case. Its core audience is also its physically oldest audience. Older people run older rigs for a variety of reasons, often related to financial or adult circumstances. If WoW were to edge out a significant portions of its base with advancing, that would be fatal. Like the equivalent of newspaper comics mostly read by old people suddenly requiring a brand new smartphone and familiarity with Linux. The Doonesbury comic may seem immortal, but this would kill him dead.
