Software: How Funcom Squashed Bugs With Bugzilla (GamaSutra, free reg required).
There’s some differences between the commercial and free-software development styles; writing games is probably one of the most extreme of the commercial development environments, with extremely aggressive schedules and a single, long-term product development arc building up to one really big release.
A really good way to use bugzilla is to track development — essentially, using it to track work instead of bugs. In other words, when work is planned, a bug is created to track that work’s progress and provide a forum for discussion of the work’s design, implementation details, etc.
This article gives a great overview of the additions Funcom have made to Bugzilla to do this, including time estimates, MS Project integration.
