The Archimedes introduced ARM, which is quite a decent legacy imo. Yet few of these British machines ever made it to the continent. No idea why. Amstrad/Schneider CPC is the only one I remember, and IBM clones were much more common.
I'd say American and Japanese studios like SSI, Sierra, Nintendo, Square Enix, etc are/were generally more inclined to produce long winding series. I can't think of an European studio that made more than three parts of a game. (Ok Settlers, but then?)
Btw, nice interview. It's really good to see that the people who made the games are real persons after all, (which is the concept of MattChat as far as I understand it).
