If you mean Thrill Kill, it was not a japanese game, and it was killed by EA. I forget the name, but it was a fighting game combined with S&M and the "kill moves" looked like some bizarre sex thing. Then again, I just remembered that you're off in Japan (haha, reading that you were near Hiroshima and such helped my memory) which means you're bound to see some weird stuff there that wouldn't be sold openly here. This is pretty odd, but I still wish that one PS1 game had been released. it appears they have somehow merged a hentai game and a fighting game. The pictures on the site don't look like anything special. So I gather instead what you are saying is that you have no moral objections to the game? what would not purchasing something that you have moral objections to have to do with censorship? That's pure market capitalism all the way. it's not like their target audience is interested in looking at penis, ne? Weird ass censorship they got going on, ne? Oh, they do that standard hentai thing of making the penis some invisible, shadow organ, which has always weirded me out. (Not like I could play it on this dang laptop.) I could use this as a nice example of how anti-censorship I am. The retail is 8000, but the store listed it closer to 6000.
They didn't have any copies in, though, which is too bad. The graphics looked pretty g'damn high end though, but with really low sysreqs. If you did the same on the control pad (they were assuming a PS-alike like the Gravis Gamepad Pro) you would fondle the breast to the right, instead. There was a nice description of some of the things you could do after you won (not much on the fighting, d'oh) and it included things like showing that if you ran your thumb around the controller in a clockwise motion, you would fondle the breast to your left in a clockwise motion. Yeah, it's pretty much as bad as you thought it could be.
I was at a local electronics/game store the other day in the adult section where my SO was picking up advertisements (she loves that free hentai) and came across a full advertisement for Battle Raper.
