It's going to take some time for me to respond to these questions, and right now, time is a commodity that I don't have very much of. If you reach out to me again in mid-April, I may have more time then. In the interim, you may want to check out the interview I did here...
...as well as my most recent Vs. Mode exchange with Stephen Totilo, here...
The gamecritics interview was especially interesting in its summation of N'Gai's feelings on the "games as art" arguements made. The Vs. Mode exchanges are interesting in their own right, and you can certainly tell that N'Gai and Stephen know eachother well.
Hopefully, all of you Wellspring readers out there will enjoy the good read too.
