So, first of all I didn't actually play this, just watched someone try. There was SO MUCH text on black background, up to the point of literally an ENTIRE chapter of Romance of the Three Kingdoms. Game design 101, Show don't tell. There was so much missed opportunity to translate an epic tale of war, betrayal and regicide and not even a tiny bit of that came through. The translation was rough, to the point that there was a lot that was not even translated at all, but that could be forgiven if the game was engaging in the slightest. It wasn't.
I really wanted to come into this not being overly harsh, because I believe that all games have the potential to be good, and I hold that true here. You have the bones of your story already told for you, what you need to do is make the characters your own, make them engaging, make them matter. Dynasty Warriors has been a franchise for decades now, everyone knows the basics of who these characters are. Half your work is done, so make your own twist on these classic heroes, and for the love of RNGesus work on your gameplay.
