lets face it the PSP has been plagued by remakes and ports and sequels since its release, they really need a developer to come up with something to set the PSP apart, an ORIGINAL platform title.. i know that word doesnt come up much in games design these days..
What about lumines? That seems to be a good original title for the PSP.
I was thinking the same thing. But I think he means that the platform needs a Zelda, Mario, or Crash, or something like that. An original platform mascott/evangelist. Many of the titles for the PSP have been seqels (Metal Gear Acid, Ridge Racer, GTA (soon), Wipeout, Madden 06 (soon), Street Fighter (soon), Metal Gear Solid (soon).
Mercury is a kinda a Lumines sort of title and it's fairly unique and awesome too. Think Marble Madness but with phenominal graphics and physics.
I can't spend that kind of money on mobile gaming. I don't actually have many opportunities to play games on the go, and when I do, a gameboy sp will work nicely for a fraction of the cost.
I generally focus on dead platforms (SNES, NES, PSX, etc.) and MAME. I don't generally get into the cutting edge because of the ongoing cost. I don't have a cube, Xbox, or PS2. So my PSP fills that modern home console void and it does it really well. But it's as a mobile device (game player, movie player, MP3 player) that it's really justified for me (business travel).
