What constitutes classic gaming in your mind, right now?

[Sightless]

Retro doesn't mean old. Retro means it's in the style of old. Pac-Man, Tetris, and Pong aren't retro games, they're old games (Or, if you want to give them some more credit, they're vintage games). They can also be considered classic games (more on that later). Super Meat Boy, Lone Survivor, and other new games with those old school graphics and mechanics are retro, because they aren't actually old games, they're just acting like it.

Of course. You're still not being clear in addressing the question about where a line is drawn, though. Retro games depend on age, but do you measure that in terms of years ago, years from the most current console, in generations, technological advances, or something else? What is "old school" (in this context)?
