I don't own smash yet, so it doesn't really affect me. Buuuuut....
Comparing prices to other fighting game DLC (looking at you mortal combat) it's completely in line with what the industry usually charges, or even a little cheaper.
However one might argue that 3-5 Dollars isn't really that great of a value per fighter anyways.
This is where Mario Kart 8s great DLC comes in. It has such great value for the price, naturally one can't help but compare that to smash DLC. It makes smashes pricing scheme seem bad by comparision. And while I like the flexibility of choosing every fighter/stage/costume on it's own I would like a pack with all of the dlc released so far,priced at about 15 dollars. I feel like that would be about on par with mario Kart dlc contentwise as well as pricewise.
