| Computer Entertainer reported in November 1986 that the U.S. division of Capcom had announced its first conversions of coin-op games for the Commodore 64 and 128: 1942, Gunsmoke, and Ghosts'n Goblins. Its January 1987 review called the Commodore 64 game an adaptation of Capcom's own arcade game. | p. 9, Critically Speaking, Commodore 64 Compatible | Magazine |
| Computer Entertainer's January 1987 review of the Commodore 64 version rated it three and a half of four for graphics and for game play and recommended it at $29.95. It found the graphics clear and well animated but less detailed than the NES version's, with fewer screens, which it was told came from the limits of disk capacity, and called it "a great arcade translation" for anyone without the NES game. | p. 9, Critically Speaking, Commodore 64 Compatible, ratingsp. 9p. 9p. 9p. 9p. 2, The Rating System | Magazine |

| Computer Entertainer reviewed the NES Gradius in January 1987 and recommended it, at a suggested retail price of about $35: it found the game challenging in the extreme and not for beginners, and, for players who like fast shooting games, one of the best it had seen. | p. 12, Critically Speaking...Nintendo Compatiblep. 12, Critically Speaking...Nintendo Compatiblep. 12, Critically Speaking...Nintendo Compatible | Magazine |
