I don't think you can calculate the name's value just on the basis of numbers.
There comes a point where you buy yourself a pillar in an industry simply by the sheer enormity of the purchase and significance of the declaration.
You can be certain that the buyer started with a semi-rational calculation of its value and as the process wore on, upped their bid to a much higher multiple. That's how a player thinks.
What's interesting to me is how underreported the sale is: I would have wrung a lot of publicity out of it, tied it into an opening cross promotion right in the release, and watched as the first couple of million got covered by it all.
Either way, kablam! Is it worth it? Who knows?
