The guys at PCGamer are dribbling out their Jay Wilson interview with another news piece this evening which includes comments from Jay regarding the fact there is no mod support in Diablo 3. When asked why there was no support, or plans to support mods, he added:
I know people look at Blizzard and say “Well, you guys are so big and have so much money you can do EVERYTHING for your games, right?” and the answer is no, we can’t. There’s so many things that we would like to do, that…time and resources; they’re real for us as well, so that was one of the things where we said ‘You know what? Diablo’s never supported mods.’”
As the author points out “Of course, it’s never supported broadband connections or real-money transactions either…”, which you have to admit is a valid point.
