Cho Aniki actually came out the same exact day I was born. Yes, I know my profile says Dec. 3, 1992, but I was 15 back then and embarrassed of being born on Christmas. My real birthday is December 25, 1992. The first Cho Aniki came out for the PC Engine Super CD-ROM 2 on that exact day. Keep in mind that in Japan Christmas is not a major holiday like it is in the Western world.
I've never played Cho Aniki. I don't have any real interest in playing it. It looks like a generic shooter. I could play a similar game without it having any ribaldness. But maybe I should track down a copy and get it... even though I don't have a PC Engine Super CD-ROM 2. I don't even have a PC Engine, but I do have a Turbo Grafx 16.
