At this stage the 16-bit Commodore Amiga and Atari ST, along with earlier 8-bit consoles and computers, were already dominating the European video game market, and hype for new 16-bit consoles such as the Mega Drive was starting to rapidly grow. Amstrad also lacked the marketing power to compete with the producers of the Mega Drive (released in November 1990 in Europe) and eventually the Super NES.[1] On top of this, there were also problems with software manufacturing, with many companies complaining that the duplication process was taking months instead of weeks,[10] leading to little software available at launch, and some games being released late or cancelled entirely. Lastly, many GX4000 games were simply CPC games released onto cartridge with minor or no improvements,[3] which lead to generally unimpressive looking games and consumer apathy, with many users not prepared to pay £25 for a cartridge game that they could buy for £3.99 on cassette instead.
