There is your problem.
VGChartz doesn't count a majority of PC sales (digital).
PC currently has more gaming hardware/software revenue than 6 other systems (consoles) combined. The proof is linked in previous posts where someone else wrongly used VGChartz for PC. And lol VGchartz.
It isn't "wrong" to use VGchartz. Physical in store sales is what retailers and distributors use as a ph strip to determine trends. Actual industry professionals still view physical in store sales as a more pertinent number than digital only sales.
The revenue claim for PC being stronger lumps in various genre that don't even exist on consoles today as well all PC related products, not just software. So when a company purchases a bunch of quad or six core CPU's for offices, BOOM, PC sales lumped into total revenue for the market-share. It's a skewed and biased analysis that only leads to fanboy forum rage. The point is, this game (specifically Dragon Age) makes a LOT OF MONEY from console sales. More money in the console market than it does in the PC market directly.
Not lumping every MOBA and microtransaction game that is available on the PC. Not lumping in every single add-on, accessory, upgrade hardware for the PC. Just apples to apples, game to game.
This is why Bioware optimized for consoles. To make sure that portion of their market was secure.
If the argument is "noooo, more stuff is sold on the PC across the board" - then yes, you're right. But it really has little to do with this game specifically, or action RPG's in general.
