Yeah, site news today! This is a very great day for the PSP. 2 great announcements.
I think I read somewhere on this site that, with all dummy files removed, FF7 is only about 450 MB total. That would easily fit on a stick.
I would love to be able to play tekken 3 or soul blade on an emulator, or better, as an official release, but the franchises have changed since those games were released. The Soul Edge series changed it's face in a big way with Soul Calibur, so, with Soul Calibur 3 on the way, Soul Blade seems kind of silly. The newer generation of SC2 players will be missing their favorite characters, and may not even recognize the game as a precursor.
But there's no reason they still couldn't release old games as new again. Look at the GBA NES classics collection. I'd pay for Tomb Raider or Destruction Derby or Twisted Metal 2.
Of course, bringing out classics at this early stage in the system's life would be a sad move, so as to say "We're giving up on pushing this systems potential, and retiring it, but here are some 7 year old games."
