I see it being bad. Most people with a PsP or DS (and mind you, I said most) are basically children.
Most people with DSes are actually probably considerably older than you or I am. They aren't that interested in this sort of thing either, but either way what you're saying makes no sense. You're arguing that they think games need great graphics or they svck... and yet the DS isn't capable of particularly great graphics (there are exceptions, but its best sellers are not exceptional-looking games), and several other games that are either ports of older titles or games done in the style of older titles have done well on the platform. Similar situation on the PSP, really, with the success of games on the platform being seemingly unrelated to their aesthetics.
Really, it might be best to do some research before making statements like those in the future.
