Message transcription Mmm-hmm. This song brings me back... Those were the days! Everybody was a pro then... Nothing like THIS team. It's finally over... Now I can settle a few scores! You're first, bitch... Yes, you! Kaoru Ogura! Running off with some guy during the development!? Hey, I don't care if you fuck him six times a night. Just take a SHOWER before you come back in to work! Now you! Yeah, I mean you, bitch! Tatsuya Omachi! There's no place for your flippant shit at work. You waltz in late the day we SHIP THE ROM!? Unforgivable! No matter how many more porno mags you lend me! And all that weight you put on...? You paid 18000 yen and all you got was a kiss! I'm not surprised! Kenji Takano, you're just a part-time debugger for Namco... You shouldn't be nitpicking about our project! Then there's Kiyoharu Goto. Yeah, I mean you, bitch! You were the biggest thorn in my side! Oh, if I had a time machine! I'd send you back to the samurai days! You can solve your fucking riddles there! Ahh, it feels so good to get that off my chest... Nope, still not done! Kiyoharu Goto! Yes, I mean you AGAIN, bitch! Arrrgh! Just die, already! But you know, there were some people who DID help. Like Okada, who only took the good parts... I know you have a freaky side to you, though. Yamagishi, you swore off sex joints until we finished. We're all done now, so knock yourself out, buddy. And Iwata, who came in part of the way through... You worked your ass off. Sorry I yelled at you, and best of luck in the future. Udopyu Fujimura... You dealt with the absolute worst shit. Thanks. I mean it. Goto's the one to blame! So many more good folks... Takayama, Kudo, Suzuki, Makki, Kaneko, Aihara... Sato, a true angel in my heart... And Iga, too. Thanks, all of you guys... And I enjoyed working with you. Yoko-G. This game is dedicated to your wife, on her birthday! Kazumushi... Sorry I didn't come back home that much... But I love you... and I always have.
