Back in the days I never bought Amiga software for two reasons: I got the crack even before it was reviewed in magazines and games appeared months after the original release in The Netherlands. Add to this the fact there were not many shops which sold Amiga games.
Anyway, I have bought only one Amiga software package once: Technosound Turbo
: a great soundsampler with some software included. Oh yeah, I also bought a PD C64-emulator once for Amiga. It was called A64
and was painstakingly slow in loading games and refreshing screens. The average speed was 10 seconds a frame with sound enabled.
