What do you consider to be retro? Certain games magazines refer to anything of the previous generation as retro, some even going as far as to include the Dreamcast. I find this very difficult to comprehend. The idea that Crazy Taxi or Soul Calibur can be considered retro is strange to me. Even the earliest PSOne games don't strike me as being particularly retro.
My very first console was a Sega Mega Drive/Genesis, although I played on the SNES just as much, due to my neighbour owning one. Anyway, I only used these consoles during the last year or so of their lifespan. As a result, I consider anything of that generation or before to be retro. Perhaps the dramatic shift from 2D to 3D as the norm exaggerates this feeling, or maybe it's just my personal opinion.
Anyway, enough rambling. Which consoles do you think of as retro?
