Eventually there has to be a disconnect between the project manager and the developers (in that they shouldn't be the same people.) However, where the gaming industry fucks up is that the disconnected project manager is still the one calling all the shots on the actual game development.
Yup. And it's great if you find someone that can combine the two, but it's better to be safe than sorry and easier to bring in a good project manager/business guy and let him learn the creative aspect than vice versa. While some creatives are sure to get up-in-arms about that, remember that his creative input would always be limited and team-based whereas the project management and business input tends to be solo.
It only took them about ten years to realize that releasing every game in the six weeks before Christmas was a bad idea, so I expect these issues to be addressed somewhere in 2185.
They're still stumbling with this, though. March and April became the "well, we can hit them post-holiday" time, then RDR made people think maybe that's not so; maybe that space can only support one or two titles and not multiple.
I kind of disagree with all of it - I'm looking for good games year-round. After the November games hit I'm looking for something new in December. The November games are already old (and still full price) so I'm looking for something either discounted or brand new. And then I go back and play some more Civ 4. I'm not alone.
