As an American fan, and I cant be the only one who would say this although I almost gaurantee no one at Bandai will see this, but please localize it for English! I have wanted a Kamen Rider game to play whether mobile or not forever, ever since I truly got hooked through Gaim and Ex-Aid (then went back further before forwards in continuity). Hell, make a nice Dynasty Warriors-esque game where the story is literally just a movie plot, Kamen Rider war between all the different Main, Extra and Antagonist Riders. You can technically make it even more Toku and just add DLC for Sentai characters.
these are the riders I recognise in the video, ichigo, momotaros/ den-o, genm/ dangerous zombie, hibiki, cronus, g3, ouja, diend, w, kuuga, lives, ryuki but green I think, and horobi
