Bruce Lee was just one of the first Spectrum / Amstrad games, much like Atari. Amstrad was many popular in UK, Spain, France, also Italy, also many of games was made in US of course.
Let's say Amstrad was a step between Atari and Amiga, like the Spectrum was; both had Casette64k/Disk128k versions, surprisely Spectrum survived over all of them, maybe because was easy to copy cassettes.
About Amiga, a friend of mine bougth a 512k and make all of us obsolete

In fact, Amiga500 was "the best of" on these times where one more pixel meant much. The most part of games was ported to Amiga but quickly we all moved to PC.. Anyways Amiga had during many years the best graphics.
The spanish game development golden age was in the Amstrad/Spectrum times; Opera Soft, TopoSoft, Dinamic, MicroChip, Erbe, MCM,.. did possible to distribute many Indie software around the world during years. My tribute to them.
In this link can see an Amstrad spanish game who was ported to all the platforms later in the 80's, notice the versions differences at the right.
