That's like saying every Transformer on the shelves HAS to show up in the show, and if they don't appear, their toy will never be sold.

Fourze has 40 basic switches. They didn't need to shoehorn in every stupid ass switch just for the toy sale of one switch...

The Showa Era had far less to compete with comparatively with the Internet and everything that the Neo-Heisei Era has to deal with.

I think the Gimmicks are fine, especially when you get the awesome voice actors who make the sounds like Come On, Banana Arms, TaToBa, TaToBa, TaToBa, Cyclone, Joker, Kamen Ride, and so on and so forth. Hell I think if W was around now he would have had more than just 6 Gaia Memories in the beginning.

Also I adore the Shift Cars right now. I mean the gimmicks work because we all want to keep giving them our money lol.

Yeah, that can be annoying. But people are more likely to buy something if they see it being used in something they like. That's why there's so many things that don't make sense in shows like Fourze & Gaim to make sense. Wizard can defeat his enemies by distracting them with Smell.....only once or twice though. That leads to more people buying the Smell Ring & others like them rather than not showcasing it at all, but also messing up the show by stacking the deck with the characters having so much stuff that can really be trimmed down.

I'm fine with kamen rider gimmicks as they çurrently stand expect when they introduce something really useful and then forget about. Kiva is the worst example of this for me personally and I actually like Kiva alot.

they did it with double, i mean they released more gaia memories but they didnt cram them in the story, that's a good way of telling a story and not cramming merch all over it.

bandai can still make money without cramming merch into the story, it was successful with double like i said. it makes no difference anyway because it gets used once in the story and never gets used again and they still are making money.

I wish wecould get another peripheral gimmick like Candroids, Foodroids and PlaMonsters.

Well you cant compare the toylines they put out 30 years ago to a modern one. Not only were more children being born during that time so bandai could produce less and earn a good amount of money but there were also less toylines to compete with.

Just as an example. Gaim sold incredibly well (not as well as double or ooo but still) yet it was dethroned this year as japans leading toy brand. Rider held that title for the last six years but was outsold this year by bandais Yokai Watch toyline. Like Rider this Line is based heavily on a collectible gimmick.
Toys these days are so heavily based around gimmicks that unless Kids get tired of them we wont see them go away anytime soon.

That's a bit different. I don't think Bandai expected fans to enjoy the Legend Rider Memories as much as they did. You can see a notable gap from Decade-Drive in that so far, like you said, Double didn't show off stuff like that in the season. Whenever you make a continually changing show like KR you wanna make sure each year can develop its own identity in both media & merchandise. They do a good enough job of doing so & that shows most in Double. It truly felt like a separate thing from what KR had done the previous year. The toys from Decade sold based on nostalgia from the celebration. Bandai assumed people had their fix with Decade & didn't continue on with Legend Rider toys in the show. But the sales was a big tip-off to Bandai, letting them see people still riding the nostalgia train. So they fixed that with OOO onward. That's why so many of the previous Riders come back in movies & specials (Wizard's finale even). Gaia Memories have been selling up to include Wizard for God's sake. And the way they play catch-up with the Gaia Memories says, to me anyway, that they're making up for lost ground. Whatever number of sales they didn't get from advertising Double's Legend Rider Gaia Memories they're trying to get back with all these special new sets like the 2 Complete Selection Sets. You'll notice no other Neo-Heisei season's toys have been getting this treatment. Heck, Decade just now got it after Double did, 5 years after Decade's show had ended. So I think their business decisions as of late prove that Bandai doesn't wanna lose any amount of money they could make. No matter how small the differences are between the numbers of in-show vs out-of-show toys, they don't wanna have to sweep up whatever loose change is wondering around after the toyline's main run again.

Funny you mention that, Hasbro has canceled a lot of toys and even forced writers more then once to include characters that they didn’t had time to work on properly just so they can sell the toy. Tigerhawk is one prominent example for that, and if you watch the shows you can clearly tell which characters were just thrown in to sell the representing toy. So this method of thinking was always a thing.

That being said, I don’t mind the gimmicks with modern Kamen Riders. Yes, they are obviously designed to fabricate as many toys with a relatively low effort, but if they give me an awesome show I don’t mind it at all. Because no one forces me to buy re-decos of things that should represent other Riders. But if they do something awesome, I'm more then willing to buy re-decos.

Everyone says that ever since Double, it's been nothing but gimmicks... Personally, I felt OOO was a hell of a lot less gimmicky than Double. All of the transformation items were directly relevant to the plot. Even the majority of the candroids made some logical sense within the story.
