PC gamers have made defunct developer 3D Realms the butt of many jokes over the last decade. After working on Duke Nukem Forever for over thirteen years, the studio closed down this year with nothing to show for all that time spent. And Polyphony Digital, creators of Gran Turismo, sometimes seem to be caught in a similar time warp where a day in their lives is like a week in ours. In the time between the release dates of Gran Turismo 4 and the forthcoming fifth game, competitor Turn 10 Studios has released all three of their Forza Motorsport games. Consider that Gran Turismo on PSP was intended to launch shortly after the PSP was released over four years ago, and you can imagine how some thought this game would never see the light of day.
