• Fla's   - I simply detest seeing large amounts of code in them. Doing binary diff's isn't really what I call an option when someone destroys your code or hasn't been faithfully working with source control.
• Fonts  - You have to make sure that everyone working on the project has them installed ( the PC or MAC equivialant).
• Audio - Any time you complile your app these are re-exported, depending on the project the waiting can turn you insane.

So you may say to yourself that those don't sound so bad and you know what, they aren't for the most part. I loath waiting for things over and over again, especially when there is a better way. There are workarounds for those issues, but are either convoluted, unreliable or require some 3rd party tool. Where I work I am primarily coding the game and for about 80% of the project I don't give a crap about the audio or if a particular font is showing up right or having to chase someone down to submit files to the depot. I just want to be able to test my code quickly and get back to rest of features that need implementing, so finding that PC/Mac Equivalent font or waiting and 10-30 seconds everytime I compile just sucks.

Well enough ranting.. that never does anybody any good and I'm sure for anyone reading this would prefer I get to the point of all of this.
