Speaking of which, if you find an original “Pong” that will run under XP, please let me know.

From the article:
“And instead of more realistic graphics, it ever accurately to reproduces the original Pong.” I think what they meant was that the creator was vigilant about being faithful to the original. This I applaud. I don’t know why more color, more realistic graphics, etc., is considered a virtue unto itself. Often “enhancements” just get in the way, and can even destroy a good concept. Simplicity is often an element of perfection.
