Electronic Versions of Games: Good for Business?

Here's a list of games...

1960: The Making of the President
10 Days in the USA
Ablaze!
Blokus
Citadels
Guillotine
Hansa
Jamaica
Kahuna
Kill Doctor Lucky
Mr. Jack
Settlers of Catan
Tikal
Vegas Showdown

So what is the significance of that list?  If you answered, a list of mostly mediocre Euro style games, well... I wouldn't necessarily disagree. Some of those games I don't really play much anymore or have as high opinion of as I once did when I bought them, and a few I have since traded away. But the point is that I bought them... and more importantly, I bought them after having played a version of them on my computer, either online or via software or with Vassal or some other electronic means.
