Kyoukaisenjou no Horizon, Nobunaga the Fool Recommendations
History is recreated in the far future combining both western and eastern periods of war with lots of different historical figures from different time periods
Differences: Nobunaga the Fool is more action and less comedy with ecchi than Horizon and also doesn't have strange speaking patterns
Both Nobunaga and Horizon are scifi anime where historical "characters" are present.
I feel as if there is any, ANY show to recommend it would have to be Horizon.
The blend of historical content with futuristic elements (feudal era, historical characters, mechs, etc...) can be found in both of these series.
