@konnichiwa: Are you sure that's the description of the PS2 port and someone didn't just copy what's on it to the description? I just checked the NEC Interchannel Website on Desire for PS2, and it's rated C for Age 15 and up. I am pretty sure there's absolutely no "H" scene in any of the PS1 or PS2 "H" game that were ported from PC.
The only game console that have allowed actual 18+ game would probably be PC-FX
P.S. All my knowledge come from a prolonged seesion with wikipedia that started with me looking off "Battle of Waterloo"... Gotta love how far you can get from the original topic you are looking for on Wikipedia.
I never played any H-game and never saw a H-game on PS2. My words are
coming from other people who said they saw them or own them.
I had this disscusion with Onna76 today maybe you have to PM here maybe she know more about it.
