I play my 2600 because the games CAN be replayed!
Most of today’s games have a story, and you play through the game which goes through the story. When you’re done playing a modern game you tend to have the same feeling like after you just finished a book. But when you try to play the modern game again it's just like starting a movie you just finished watching over again! You've seen it, done that, got the T-Shirt too!
With most classic games and ESPECIALLY the 2600 (because it's such a simple system) there is no real plot, just plain-'old good action! Sure there are a very few RPG style games but for the most part when you play the games just dump you straight into the action and don’t let up until you've won or lost!
And that is what I love about my 2600, when I want to get in and play it's there for me. No phony bologna story plot to have to follow, no cut scenes that I've watched a bazillion times, just the game that’s fun and addicting to play!
