Most of us here have been gaming for years, but let's see how often we really play the oldies. What was the last retro game you bought or played? What system was it on? Come back and post again when you play another one, too.
For the purposes of this topic, "retro" will mean anything released more than five years ago.
The last retro game I bought was a PlayStation game called Eternal Eyes. I found it at a flea market a few weeks ago, still sealed. It's pretty rare to find a game in that condition at such a place.
