The Incredible Hulk
The Incredible Hulk was supposed to be a video game created by toy and game manufacturer Parker Brothers in 1983 for the Atari 2600. The release of The Incredible Hulk was scheduled for Autumn 1983. However, this period coincided with the video game crash of 1983 (following E.T.'s release in December 1982). During this crisis, numerous companies, including Parker Brothers, opted not to launch games that had already been developed for the Atari 2600. Consequently, The Incredible Hulk was never made available to the public.
Play to Befriend a Pokémon!
Play to Befriend a Pokémon! was a Flash game formerly available on Pokémon.com. It was a Pokémon Global Link promotion. The goal is to break blocks with a bouncing ball, similar to Breakout. Players use the paddle to keep the ball from falling out of bounds. When the ball hits blocks consecutively, the score increases by 100 each hit. Sometimes when a block is hit, an orb of its color will fall. These orbs, when caught by the paddle, are worth 500 points each. There are 4 levels, and the player starts with 3 lives. They may earn more lives and power-ups later. After playing, the orbs caught, depending on what kind, can be used to redeem 1 free Pokémon via the Pokémon Dream World, provided the player is signed in under their Pokémon Trainer Club account. These Pokémon are Vaporeon, Jolteon, Flareon, Espeon, Umbreon, Leafeon, and Glaceon. The game was removed after May 19, 2011, and the .swf file for it was actually deleted from the site.

Yeah Yeah Beebiss I is a rumored lost game for the NES that was first mentioned in the June 1989 listing for mail-order video game service, Play It Again, where it would reappear until September before being removed from the listing and then show up on another mail-order video game service known as Funco. There's no known information about the game other than it's title, however there are various theories to the game, from it being a mistranslation of a Japanese game, with the most popular theory for this one being the game Rai Rai Kyonshis: Baby Kyonshi no Amida Daibouken, to the game being a copyright trap made up to spot other magazines who were copying them. As of 2022, none of them have been confirmed.
