Why can't MGS, FF, GT sell as much on PS3 as they did on PS2??

[memory2zack]

doesn´t casual mean that it appeals to everyone? Sales haven´t to do anything with that.

The definition of niche, like you said, is that it appeals to a certain audience.

Therefore my deduction that not-niche=casual.

 

Edit: in simpler, more understandable words?
