Xbox 360 and Playstation 3 can be considered Retro, and by that extension all the games from its era. Both released about 20 years ago, discontinued 10 years ago and since then 2 generations of new consoles appeared. But games like GTA 5 that are developed, re-released and sold to this day, I wouldn't consider that game to be Retro. And that's one of the problems with evergreen running games.
