Polyphony Digital, the creators of the Gran Turismo franchise, have announced that the recently released Gran Turismo on PlayStation Portable has managed to sell over 1.8 million units since its release.
The game has only been available since October 2009, but that hasn't stopped it becoming one of the best selling PSP games despite lukewarm reviews. Polyphony Digital also announced that Gran Turismo 5 "Prologue" has almost reached the 5 million sales mark worldwide - not exactly bad figures for what's essentially a glorified demo. Complete franchise sales can be viewed by clicking the source link.
The last major release on a home console came way back in 2005 in the form of Gran Turismo 4, and it looks like gamers might have to wait until the end of 2010 to play the next iteration in the franchise. Hopefully the wait is worth it.
