There is anger from Amstrad users in general, because they feel that if more time had had been taken on the Amstrad version, we could have had a version that used the abilities of the Amstrad better, looked better, perhaps sounded better, and played as well or better than the Spectrum version.
It is worth noting that Spectrum ports also existed on [[MSX]], Enterprise and C64.
=Reasons=
The [[ZX Spectrum]] shared similar hardware with the Amstrad CPC (see Machine comparions).
The Spectrum was very popular and with the CPC having a much smaller market share, so it made sense to develop the Spectrum version first and to save on time and money, the Spectrum code, music and graphics were re-used. (A typical port to the Amstrad is said to have been done in 3 days so was financially good. Spectrum ports also existed on [[MSX]], Enterprise and C64).
This phenomenon was more prominent in the UK, where the Speccy was the dominant machine. In other markets, such as France of Spain, where the CPC was very popular, games were coded from scratch for the CPC, often using an [[Atari|Atari ST]] for [[Games Crossdev|Cross Development]]
