The Adventures of Rad Gravity is a video game for the Nintendo Entertainment System developed by Interplay Productions and published by Activision in 1990. The game is a platformer with a wacky storyline in which the eponymous main character explored multiple planets and fought enemies while jumping through levels. The story is that in the far future, humans colonized many planets and established a form a biotechnology, which were sentient beings called Compuminds, which could communicate rapidly from world to world. The game's villain had shut down all the Compuminds and hid them. Eventually one of the Compuminds, named Kakos, was found. Rad Gravity is the name of the game's hero. Together, Rad and Kakos must find the eight missing Compuminds, each on eight different unique planets, such as the cyberpunk world of Cyberia, the green jungle world of Sauria, and the caustic trash world of Effluvia. The game was notable for the planet Turvia, where gravity works in reverse. In that level the protagonist was drawn upside down, as were the enemies and the entire screen. The main character has a comically large head and strongly resembles actor Bruce Campbell. His early game attack consists of a sort of a lightsaber. The Adventures of Rad Gravity received overall generally positive reviews, and Simon Burns of VoxelArcade called it 'one of the most interesting and innovative of NES games' in a retro feature.

The Castlevania titles have been released on various platforms, from early systems including the Nintendo Entertainment System to modern consoles.

City Connection (シティコネクション, Shiti Konekushon?) is a video game developed and published in 1985 by Jaleco for the arcade in Japan and published by Kitcorp as Cruisin' outside of Japan.

The car normally moves at the same speed, although the player can push in the direction the car is moving to make it drive slightly faster.

The object of the game is to drive through a series of cities and paint every part of the roads in each city as proof of the player's visit to that city. City Connection was remarkable for its time in that each location had its own background and music which was a variation on the main theme of the game. There are twelve locations: Manhattan, the Grand Canyon, Easter Island, Paris, Neuschwanstein Castle, London, Sydney, Egyptian temples, and cities in India, Holland, China and Japan.
