That is often why I think Kamen Rider never really took off and why some of the most often picked series for adaptation from fans are some of the worst.

Just think about OOO, probably the most voted series for adaptation from fans, now really think about HOW MUCH you can actually use. Even ignoring how little action that show had comparatively to sentai, Ankh is integral to the mythos and is basically entirely unusable and that isn't mentioning that every transformation in that show is done in real time.

Your average sentai episode provides about 80% usable footage, I'd say your average Rider episode has about thirty percent, AT BEST. Shows like Fourze for example, is set in a JAPANESE high school, you'd probably have to reshoot way more than seventy percent of that, I'm sure. That is why I think sentai worked and Rider never did.

It also makes sense of why they picked Ryuki, the more Riders = the more footage they have to use, it just makes sense even if you think about the tone, or theme or whatever else. If any show is to be adapted at all, I'm guessing it'll be Kabuto as it has the next most amount of Riders other than Gaim.
