Basically the code geass alternate history is one ofthe most retarded things I've ever seen in an animu. the premise is fairly simple: america never hasppens and napoleon is never defeated, forcing the british to relocate to the new world. hovever the geass writers have seelingly completely ignored the other consequences of this happening.
There would be no louisiana purchase, no congress of vienna, no revolutions of 1848, no unification of germany, no world wars, no cold war; basically everything needed for the britannians to become a powerful empire never would have happened. it's like the writers never bothered to open a history textbook.
the shit is so farfetched, why do they even use an alternate time line at all? why not have an advanced timeline like gundam, or a completely different universe like the ace combat vidyas?
