What does that word mean when it comes to games? Everyone has their own ideas of what is retro depending on age and they are all different. Even the grubby teen can now look back and call some PS3 games 'retro' as indeed they are to him/her. For some though, retro really just means pre-3D where games were almost exclusively 2D pixel art and custom sound chip all written in mind bending assembly code so hence this will be the temporary definition of 'retro' for this article alone.
