If I remember correctly, I saw some male genitalia in GTA V or IV on Xbox 360. Probably V, since it also had female nipples exposed.
About the polygon SF games, well, their graphics style is not my taste. I stick with Super SFII the New Challengers on SNES, which also had nicely drawn character art beside pixel graphics. When the series went Alpha, the character style became too much Anime for my taste.
Yeah, it might be allowed now, I'm not sure what's needed but it's probably still unusual.
