For those who don't know,
Amstrad is a UK-based electronics company founded by Lord Alan Sugar (best known these days as the host of the UK version of 'The Apprentice') and best known for their CPC home computers from the 80s. Nowadays, they mostly make stuff for Sky Television (Set Top Boxes, etc), but back in the day, their computers were to us what the Commodore 64 was in America, i.e. a very popular gaming computer.
What many may not know is that, as well as gaming computers, Amstrad also tried to enter the console market with the
Amstrad GX-4000 in 1990. The main reason many may not know this is because it was a colossal failure, mainly because...
1) It was an 8-bit console released at a time the 16-bit Sega Mega Drive had already been released and the Super Nintendo not far behind.
2) It only had 25 games made for it in its entire existence.
3) Most of those games were already available for the CPC computers, with the Cartridge versions for the GX-4000 being more expensive than the computer versions.
In the end, the GX-4000 sold somewhere between 10,000 and 20,000 units (depending on the source - the 15,000 figure currently given on Wikipedia seems to be the most commonly given figure) making it probably the biggest commercial flop in console history (even the Apple Bandai Pippin sold at least two-to-three times that).
Afterwards, the closest Amstrad got to the console market was the obscenely overpriced 'Amstrad Mega PC' which had a built-in licensed Mega Drive and was initially priced somewhere in the region of £1,000 (needless to say, it didn't sell well).
So, your challenge, should you choose to accept it, is this - make Amstrad a major and successful console manufacturer, whether it be via a more successful/better thought out GX-4000, a breakout successor to the GX-4000, or by some other means. Bonus points if you can make that success worldwide and last to the present day.
