Metal Gear franchaise for the Playstation. Alot of games are exclusive to that particular company.PS=Japanese Final Fantasy games and Xbox360=America Halo games.
But if a game does goes to multi-platforms like Ironman + the Hulk there's more stages for the higher memory consoles=PS3 / Xbox360 than the PS2 or Wii,DS,PSP,GBA. Plus the cheat codes will be different buttons configuration.
It's best to know a game hacker and download with a emulator...so you can play all the old system and games from the original nintendo,snes,genesis,intellvision,coleco,commandor64,ps1andsega
I got the regular edition..don't feel like paying an extra $20 for the collector's edition.At EB Games.
The creator of MG, Hideojima felt 50gb is not enough memory for the PS3 and the artwork for the Americain release sucks.
