My recollection is that only the Amiga versions were distributed through EA. EA made a major commitment to the Amiga, whereas we really didn’t focus there, and our the Amiga version of our products generally weren’t that great. We did some great product for the Amiga, like Frogger, but overall, we didn’t make the same level of investment as EA did — so, it made more sense to use their distribution than our own.
No one at Sierra liked the idea of distributing ANYTHING through a competitor. I saw it as EA’s fair reward for having done a great job on the Amiga. Our relationship with EA didn’t last long.
