This is great.
It'd be nice to have more game commentaries like this but this one is so loose and enjoyable.
Speaking of which, I love hearing devs talk about their own games unfiltered and completely removed from trying to market the thing. Specifically I like when they discuss the things that 'went wrong' so I thought I'd point out some more:
Ratchet & Clank 2: Going Commando

Former Insomniac devs Tony Garcia and Mike Stout (one was a junior programmer the other was a junior designer, I couldn't tell you which is which offhand) play through, reveal some behind the scenes info, get into how the game works and why it works the way it does, and spend a lot of time shit-talking their own work.
Ratchet & Clank 3: Up Your Arsenal

Same guys, but they were upgraded to non-junior positions for this game and therefore their breadth of knowledge on the project is slightly expanded and they're more proud of their own work on this one.

Unfortunately this commentary is just on the cutscenes for some reason, but it's still fun to hear these guys talk about such a big-name title like it was a job. They make fun of themselves a lot.
Halo 2

Just the cutscenes again, but this one is really interesting because it's very clear that the people on mic aren't pleased with how the game turned out. They mostly talk about content that had to be cut or changed, issues with the story not making sense because of whole chunks of levels being cut, and they do so pretty frankly.
If anybody knows of more like this please share.
