This guy is silly:
Single player games will always have an audience. The sales of the Nintendo DS have indicated that pretty clearly, among other things. Even in the MMO space, Blizzard finally understood that the solo player is valuable. ArenaNet knew that all along.
Don’t even get me started on his typical industry-popular hatred of used games. News flash, Perry: Not everyone is an early adopter, not everyone who isn’t is a pirate. Price your games well to start with, and the sales will come. (Especially for the next few years, maybe longer with stimulation.)
With professionals like this, I’ll take more armchair designers, thanks.
