Regarding some games of my childhood:
Lula: The Sexy Empire (also known as Wet: The Sexy Empire) is a business simulation game for Windows. The game revolves around building a multi-million dollar erotica industry.
[WIKI] Carmageddon is the first of a series of graphically violent driving-oriented video games produced by Stainless Games, published by Interplay and SCi. It was inspired by the 1975 cult classic movie Death Race 2000.
[WIKI] Blood is a PC game developed by 3D Realms and Monolith Productions and distributed by GT Interactive. Development was underway at 3D Realms in parallel with a number of other well-known titles.
[WIKI] I also remember playing a bootleg game for Sega Megadrive that i could never find emulated.
It featured a witch, hunting hideous creatures on a scenery containing fleshy walls giving birth to babies that you had to dispose of.
I wish i could go back in time and get my hands on that cartidge. It was a multi-game bootleg of awesomeness!
In my opinion, most of the successful games produced in the 90's were all about controversy and violence.
