@Hisiru- i will agree with you that the PSP has alot more potential then the DS that the dev's simply aren't taking advantage of overall just yet... however...
Dragon Quest IX/FFIV/Golden Sun, is all a matter of opinion, same goes for my phantasy star portable 2 post earlier, the dif is though i've pretty much seen what the DS has to offer graphiclly, its decent but a does not come close to what PSP is capable of, and to be honest i also give PSP more praise then the DS for the simple FACT that the PSP is the only handheld to not only SURVIVE against a Nintendo based handheld gaming device but its also taken away quite a handful of exclusives that COULD have been DS exclusive but since PSP is around that didn't happen.
For Example, if it was only DS, chances are Phantasy Star Portable 2 would most likely be Phantasy Star DS 2, but again, since PSP is around THAT did not and WILL not happen.
Anyways, i hate monopolys, and nintendo has had its crown for far to long when it comes to portable gaming, and in MY opinion, i feel Sony has done portable gaming better then the Nintendo has done with the DS this gen, im not saying the DS is bad, just PSP is better for various reasons, exclusive games like PSP2 being one of those examples. along with Crisis Core and Kingdom Hearts: Birth by Sleep and many others.
