I wonder if there's any source of information where I can get specific examples of this issue. It would be quite curious to see side by side comparisons on how stories differ, and see if there's any general trend.
It's not a "source of information" but a "specific example": the robotech RPG manuals (or at least some of them 90's editions, not the main one but the companions) had an appendix where they delved into the differencies between the US and Japanese translations.
Looks like not just technical terms, but some plot lines diverted fairly from the original
Wouldn't that have to be the case as Robotech is a US combination of 2 unrelated Japanese cartoons?
