Today, retailers won't carry a game that receives an ESRB rating of "Adults Only" so video games very rarely receive this rating. Developers will alter the game to get back down to a "Mature" rating and ensure customers can actually buy it.
In the 70's, 80's, and early 90's there was no ESRB, but adult video games were still not very common. Many retailers wouldn't sell them and console manufacterers wouldn't grant licenses to adult games either. A few adult video games were made for consoles though and quite a few of them have become rare and very valuable as collectibles.
Below is a list of the rarest and most valuable adult video games:

Peek-A-Boo Poker is a five card draw poker game with different erotic reward scenes for every $1,000 in winnings. Each scene is a picture of a partially clothed woman with a phrase riddled with sexual inuendo like "I know you have a Straight for me".
Peek-A-Boo Poker was published in the United States by a company called Panesian, who also released three other games on this list. The game was only sold via mail order to video rental stores. It was never sold to the general public and only avaialble via rental until rental chains started selling off old games they could no longer rent.

Hot Slots is a slot machine simulator with partially nude images as rewards for different monetary milestones. The more money you earn the less clothing is shown in the reward images. Each image also has a thought bubble, which usually contains a double entendre like "Get ready to score my jackpot."
Hot Slots was also developed by Panesian and like their other two games is available in very limited quantities. Complete version of the game include a one page instruction leaflet that explains how to play the game. That one piece of paper can increase the price of the game by $200-300.

Bubble Bath Babes is similar to Tetris and Puzzle Bobble. You rotate rising bubbles of different colors so more than four bubbles of the same color are touching and they disappear. Like the other two Panesian games, the nudity occurs after receiving a certain score.
All three Panesian games were unlicensed. Nintendo wouldn't approve publishers making adult video games, but Panesian was able to release them without the license. Being unlicensed limited the distribution channels and production capabilities for the game, which helped make it very rare.

In X-man you must manuver a man through a maze avoiding crabs, scissors, and teeth until he reaches a pink door in the middle. After reaching the door you are rewarded with a simulated sex scene.
X-man was the only game published by Universal Gamex. It sold very poorly because it wasn't covered by the gaming press or sold in many retail stores. It is considered one of the rarest Atari 2600 games of all time.

Bachelor Party is similar to games like Arkanoid but instead of a ball bouncing around the screen it is a man and the blocks are replaced by women in a "sexy" pose. The graphics are so poor that it is hard to even tell the "sexy" pose is even a woman.
The game was developed by Mystique, which sold its games as "Swedish Erotica" even though they were made in the USA. The company went out of business in 1983, along with most other video game developers of the time.

Another double sided cartridge from Playaround featuring Philly Flasher and Cathouse Blues. In Philly the Flasher you play as two men who try to catch a woman's breast milk as it falls down the screen.
In Cathouse Blues you try to score with seven different woman but must remember which house they live in without going into the houses with alarms. Along with all other Playaround games, this one sold very badly when initially released and is renowned for its horrible game-play.

Custer's Revenge was developed by Mystique. General Custer must dodge aerial attacks to make it across the screen and have sex with a naked woman tied to a pole.
Custer's Revenge was the very first video game controversy. The game looks like it depicts Custer raping Native American woman. It was renounced by many women's groups and Native American groups soon after its release. In spite of the controversy and publicity the game sold poorly.

After Mystique closed down, they sold their game rights to a company called Playaround, who used the game concepts to make some of their double sided Atari 2600 games. This double cartridge includes Beat Em and Eat Em (originally released by Mystique) and Lady in Wading, which is the same concept as Knight on the Town but with a female lead.
In Beat 'Em and Eat 'Em you play a naked woman who must catch semen before it hits the ground. It is infamously known as one of the worst games ever created.

The last of the Playaround double sided games to appear on the list. Bachelorette Party and Burning Desire mimic concepts seen early in this list but with the roles reversed.
Bachelorette Party is similar to Bachelor Party but with a woman bouncing around and hitting naked men. Burning Desire is like Jungle Fever but you are a man who must use his semen to put out the fire instead of using breast milk.

Riana Rouge is a full motion video adventure game with full nude death scenes and horrible acting. A woman is pushed out the window after accusing her boss of raping a fellow employee. During the fall she is transported to another world where she becomes a seductive warrior.
Riana Rouge is one of the few video games actually released with the "Adults Only" rating. Because of the AO rating, the game was never widely distributed and sells very rarely in the secondary market.

The Guy Game is a trivia game with live action footage of women in bikinis after every question. The footage was shot during spring break at South Padre Island. When the game starts the breasts are blurred but as you answer more questions correctly they became uncensored.
The Guy Game was pulled from retailers shelves after a female contestant on the game revealed she was only 17 at the time. Lawsuits insued and a judge granted a restraining order which prevented the publisher from selling or distributing the game anymore.
The list is ranked by the highest average price for the game in complete condition (includes the original game, case, and manual) and then highest average used price in the event of a tie.
