Oh I'm sorry if you prefer having inferior sound and graphics. To me the DS does not have "reasonable" graphics and sound. The Sega Saturn had "reasonable" graphics to the PS but not to the N64.
Nope DS is too big, no discussion there. Clamshell design is nasty in my opinion. It like one of those new cool mini laptops. Except they're proper computers with keyboards while the DS is just a slightly smaller N64.
Unless you smack the PSP into the ground, your not going to damage the screen. I've treated my PSP like shit and its holding up fine with no scratches. Bit dirty though.
Actually number 4 is not graphics. Its limitation of the hardware and software.
Mario 64 is still a port, if it was completely changed it would warrant full price, otherwise it should be a budget title. Wario Ware is like the GBA game shifted to the DS.
Of course PSP games are more expensive. I mean, like 4 people could make a DS quality game if they tried, while PSP games have you know productions costs. Its expensive to make games with near PS2 quality graphics, CD quality music and FMV. I doubt DS games cost too much more to make than GBA games.
hell I'll pay $100AU for a PSP game like NFSU Rivals any day, while DS? $50 max for top quality titles.
Anyway this was MY OPINION and obviously you disagree but your counter arguments have "no basis in reality." either.
