I finally found the time to listen to the whole thing. Thanks to the person who posted the link.
The interview confirms that Civ5 was developed with a design vision that simply describes a game that's not very enjoyable for me. I'm not blaming them for that. I actually understand why they wanted a more accessible game this time - it's vital for Firaxis to try to expand its audience and lure new players in, and building on top of Civ4's complexity would've made that very difficult. Still, I'm a bit sad about many decisions which (given the goal of a more accessible game) could have swung either way, and unfortunately swung in a direction that made the game less enjoyable for me. It seems that the current team at Firaxis simply doesn't share my preferences of what makes a good Civ game. That's okay (I didn't expect them to match my preferences as perfectly as they did with Civ4), but still sad.
There's one thing about this interview which I found pretty odd though.
That's the way how
Shirk distances himself from Shafer whenever a controversial design issue is talked about. You may have to listen twice to the interview if you don't catch it the first time, but I think it's pretty obvious if you know what to look for. Shirk makes a point that 1upt was something that "Jon really wanted", that having fixed policies instead of civics was something that "Jon wanted" in order to have players "invest" more into the early game, or that "Jon didn't feel" that religion would fit into design very well. However, when talking about less controversial issues, like "1 leader per Civ" (which does get mentioned here and there, but draws far less criticism than the others), then he says that "we wanted" more variety of different cultures.
I'm not that deep into games marketing to have a good grasp on how other producers talk about such things, but usually I'm hearing either a consistent "we", or the lead designer may be singled out for something that he did really well. I don't recall a producer singling out a developer specifically when controversial design issues are on the table.
If I were Jon Shafer, I wouldn't take this as a good sign ...
Edit: Ah - reading through today's new posts in this thread, I see that zonk also noticed how surprisingly often Shirk referred to Shafer. Though he's coming from a slightly different angle, taking it as a sign of either Jon's inexperience, or Firaxis' perceived failure of balancing this out with experienced team members or more tests. That's another way to look at it of course, but for me that fact that Shirk distances himself from Shafer at all, at this point, was the most surprising.
