What if WoW gets like 20 years old, and you have like 15 expansions you have to install if your computer crashes .__.
Some people might not be bothered to install
ONE SINGLE GAME
for hours on end, and then paying money to play. I'd imagine that if you have a computer crash, that might be the end of some people's WoW career...
EDIT: - and think about new players who need to go buy all the 15 expansions. That's alot of money. Or if someone wants a new account. All those CD-keys...
Let's just hope WoW lasts long, but not too long.
