3D adult game Time Leap, released in 2007, is set to have a spring 2009 sequel entitled Time Leap Paradise, which has attracted much attention by way of its similarity to Idol Master in gameplay (the characters will be completely dissimilar).

The game promises the much hankered after prospect of rearing idols and then having sex with them (where Idol Master only allows limited sexual harassment); these idols will be made to dance and attire themselves gaily in proper idol fashion, and as you can see below, the graphics look to be quite reasonable.
