MaryJane is making an assertion that I don't think holds true. He doesn't know if everybody here would want a portable GC.
While the statement that the GBA had a lot of SNES ports is correct, it does not explain the entire picture. One must remember that the GBA basically had the entire market to themselves. And even so, most of the highest rated and highest selling games on the GBA were in reality original GBA efforts and games.
In contrast, of the 9 million sellers the PSP has worldwide:
Grand Theft Auto: Liberty City Stories
Star Wars: Battlefront II
Monster Hunter Freedom
Need for Speed Most Wanted
Everybodys Golf Portable <----- This one
Ridge Racers <----- This one
Need For Speed Underground Rivals
SOCOM: Fireteam Bravo
Monster Hunter Freedom 2
only 2 can be considered original efforts. Everything else is borrowed code or the exact same game as the console. THIS is what is selling, not Loco Roco or Daxter or Ratchet and Clank or hell Even METAL GEAR and FINAL FANTASY.
And even then those two games look so much like their console counterparts, to the naked eye they appear to be nothing more than ports.
Compare this to the Huge list of DS games that have sold a million worldwide, where the only real port is Super Mario 64. This merely cements the PSP as a colossal waste of time for developers, who can only profit from porting. On the DS, originality can sell. On the PSP, it can't. So all they do is port, port, port. Seriously, look at the list of games even the more hardcore fans of the PSP are looking forward to, a remake of Castlevania: Rondo of Blood, and a port of that god-awful Final Fantasy Tactics from the Playstation. Even the FANS want ports. They can't possibly win.
