The English artist William Roger Dean (born 31 August 1944), better known as Roger Dean, is best known for his work on posters and album covers for musicians, which he began painting in the late 1960s. The artists for whom he did the most art are English rock bands Yes and Asia. And those who are familiar with these bands can see the resemblance of the artwork above. 

​Beginning in 1985 with the software company Psygnosis, Dean has been responsible for the cover artwork for several video games like the three we just got here but also Shadow of the Beast, Tetris Worlds as well as a redesign of the Tetris logo.

Here we take a look at these games individually

​Obitus is a role-playing video game developed and released by Psygnosis in early 1991 for Amiga, Atari ST and DOS systems. It was also ported for the SNES by Bullet-Proof Software. Obitus combines several graphics styles and perspectives in a labyrinth-base game. Though nearly every piece of a forest or catacomb looks indistinguishable from the next screen, this can be dealt with by the player making physical maps, using the compass. The game is heavily focused on the need to make maps. Without them, the player will die long before making it to the end. There is very little food and time cannot be wasted walking around trying to find a way forward.

​Barbarian is a 1987 computer platform game by Psygnosis. It was first developed for the Atari ST, and was ported to the Amiga, Commodore 64, DOS, MSX, Amstrad CPC and ZX Spectrum. The Amiga port was released in 1987; the others were released in 1988. Like most early Psygnosis titles, the cover artwork (part of "Red Dragon" figure/landscape)  by Roger Dean.

The game spawned a 1991 sequel, Barbarian II, released alongside Leander, and Ork, other platform-based action-adventures from Psygnosis.

Both the Terrorpods game and Barbarian are still sealed in their original packaging and haven´t been opened for almost 30 years. 

Game & Watch is a line of handheld electronic games produced by Nintendo from 1980 to 1991. Created by game designer Gunpei Yokoi, each Game & Watch features a single game to be played on an LCD screen in addition to a clock, an alarm, or both. This console inspired Nintendo to make the Game Boy. It was the earliest Nintendo product to garner major success. In 1977, Gunpei Yokoi, traveling on the Shinkansen, saw a bored businessman playing with an LCD calculator by pressing the buttons. Yokoi then thought of an idea for a watch that doubled as a miniature game machine for killing time.

​The game we go here is Fire wich is a Game & Watch game released as a part of the Silver series on July 31, 1980, and as a part of the Wide Screen series on December 4, 1981. It is a single-screen single-player Game & Watch.

The player controls two firemen who carry a trampoline and must catch people who fall from a burning building and bounce them into a waiting ambulance. The player is awarded 1 point for each person who reaches the ambulance, and loses one of their three lives for each person who hits the ground.

​The ZX81 is a home computer produced by Sinclair Research and manufactured in Scotland by Timex Corporation. It was launched in the United Kingdom in March 1981 as the successor to Sinclair's ZX80 and was designed to be a low-cost introduction to home computing for the general public. It was hugely successful and more than 1.5 million units were sold before it was eventually discontinued. The ZX81 found commercial success in many other countries, notably the United States, where it was initially sold as the ZX-81. Timex manufactured and distributed it under licence and enjoyed a substantial but brief boom in sales. Timex later produced its own versions of the ZX81 for the US market – the Timex Sinclair 1000 and Timex Sinclair 1500. Unauthorised clones of the ZX81 were produced in a number of countries.

We got this one with an extra 16K RAM expansion.

​The ZX81 was designed to be small, simple, and above all cheap, using as few components as possible to keep the cost down. Video output was to a television set rather than a dedicated monitor. Programs and data were loaded and saved onto audio tape cassettes. It had only four silicon chips on board and a mere 1 KB of memory. The machine had no power switch or any moving parts (with the exception of a VHF TV channel selector switch present on early "ZX81 USA" models and the Timex-Sinclair 1000), and used a pressure-sensitive membrane keyboard for manual input. The ZX81's limitations prompted the emergence of a flourishing market in third-party peripherals to improve its capabilities. Such limitations, however, achieved Sinclair's objective of keeping the cost of the machine as low as possible. Its distinctive design brought its designer, Rick Dickinson, a Design Council award.

​The ZX81 could be bought by mail order in kit form or pre-assembled. In what was then a major innovation, it was the first cheap mass-market home computer that could be bought from high street stores, led by W.H. Smith and soon many other retailers. The ZX81 marked the first time that computing in Britain became an activity for the general public, rather than the preserve of businesspeople and electronics hobbyists. It inspired the creation of a huge community of enthusiasts, some of whom founded their own businesses producing software and hardware for the ZX81. Many went on to play a major role in the British computer industry in later years. The ZX81's commercial success made Sinclair Research one of Britain's leading computer manufacturers and earned a fortune and an eventual knighthood for the company's founder, Sir Clive Sinclair.

Here is a picture of ZX81 sold as an kit which you had to assemble yourself :)
