I think it would be amazing if we could see the past and watch it like a movie, exactly what happened. I'd love to see how some cultures were back then, how the houses were built etc.
Ahh, the Nanboku-cho jidai was such a chaotic period and as much as I would've loved to see the Genko no ran in 1333, Nakasendai war in 1335, the Battle of Minatogawa in 1336 or the Battle of Chikugo in 1359 as well as the several battles that took place for control over Kyoto by both sides, those battles were brutal and very bloody, considering how battles changed from the Kamakura period to the Nanboku-cho period, the numbers of armies were larger and the mobilization of them had to be faster. Takauji died as a result of injuries from the battles he took part in, accumulated over the twenty odd years he spent fighting and he fought in the biggest battles of the period.
The fact that lower class samurai had to fight with everything on line because it was due to rewards they needed for the war effort they funded out of their own pockets, even dotting down random information like taking an enemy's flag to file for report, it shows just how much of a very hard time except for the big warriors at the top of the Ashikaga Shogunate or those that supported the Southern Court in Yoshino, even so, it was a difficult time all around from the farmers, to the temples all the way to the top warriors in the country at that time.
But yes, I would've loved to see things for myself instead of just reading it through books, old sources from that time period referenced in these books and blogs.
