Atari released the incredibly popular 2600 game "Space Wars" as a ROM-converted cartridge for home computers. The concept was fairly simple, and the game was a re-skinned version of the Atari 2600 game "Welcome to Woprld War", where you needed to destroy as many spaceships from the "Woprld Wreckers" in a single game. This wasn't a particularly good game, but it was relatively cheap and adapted for home computers, and it was the perfect opportunity to hype Atari's upcoming launch in the best way.
GameBlazers was a new version of a video game developed for the Amstrad CPC 464 in 1986 called "CAC Man", an adaptation of the popular board game "Castle War", which was itself an adaptation of the titular game from the board game "Mitchell". It includes the original game as well as the console version that was popular in arcades after the release of the home computer version.
The widely popular and extremely successful Floppy Disk Hero was a game made for compatibility with IBM's PCjr, released in 1990. If you would dare to play this game at home, first get a floppy disk, and then insert in the computer's disk drive. The game would then load the contents of the disk in the drive, executing in-game unless a DOS interrupt decides to load the game's content directly from the disk. Here the in-game menu is displayed by a running DOS program on the floppy disk. d2c66b5586
