Almost seems to count for a lot with "Duke Nukem Forever" as well. Here's piece of a Game Daily interview:
Miller: We've put about $7.5 million into that and we've been working on it since late 1998. So it really hasn't been that much of an investment. And once it comes out, if it's as successful as we think it'll be, we'll make that money back in the first day or two of sales.
THR: 1998? You've been working on it for eight years?
Miller: I know, I know. It's embarrassing.
THR: Maybe you can explain to readers who don't know the games industry why it should take that long to make a game.
Miller: It shouldn't. And I'm dumbfounded myself. A huge part of the problem is that it's really hard hiring good developers to come to Dallas. This place used to be a hotbed of game development. But, nowadays, people seem to want to go to Austin instead.
Hmm. Sounds odd to me. Aren't most game developers young and more easily relocatable? In any event, that game is the industry version of Waiting for Godot.
