Guys, for those of you who dont know, this is actually more closer to an EPIC fail rather than success.
Here is why:
First of all, 500 million were invested. Those were invested some time ago, and inflation would have to be taken into consideration.
Second, this was a very marketed game. That means that units will sell better at launch, and fade very fast. Usually 90% of the sales will happen in the first week, and from that 90%, 85% on launch day, perhaps day 2.
Third, Taxes have to be paid, and those are NOT lowered by previous years costs on the games production, as taxes have yearly cycles.
Now, most of those facts may change over time, but there is a reason why we see Destiny news everywhere, and how much they sale: Activision and blizzard sure would like more investors.
I dont remember Blizzard going out every year to boast about how much money they make when WoW was at its prime.
Here is the rule of money: when you have a lot of it, you keep quiet. Its when you starting to get low when you have to try to show otherwise.
You dont see many guys who win the lottery run around and scream it to everyone, do you?
