I guess if I'm being honest, my first series was Saban's Masked Rider. But I choose not to recall that certain period in my life haha.

It's in Clarksville, TN.
And it was still open the last time I went there (2008).

Oh, wow, Kuuga got REALLY good at the end, I thought. Once they stopped worrying so much about the boring people and their boring lives, and focused only on the cops and the Grongi, it was awesome. You should go finish it.

I will, I will, right now I'm watching Ryuki, I want to finish that, then go to Kabuto(I often start series and don't finish them :lol ), but after that I plan on finishing Kuuga!

My first watched Kamen Rider series was W, while my first finished series was Decade.

My first Kamen Rider show was Agito. I watched most of it on Youtube with really poor quality and at least three different sub groups. I still loved it. Finally re-watched it this year with my wife and I still love it.

My Begins Night, of sorts, started in early 2011 with OOO's first episode, but then I thought I should start at the beginning, and (only aware of the site and no others) watched TV-Nihon's subs of the first three episodes of Kuuga. Then I noticed the earliest series subbed in full was Ryuki. Ryuki makes for a good gateway-drug.

After that I started catching up with OOO, while watching Decade, then while watching W, then while watching Faiz, while inconsistently watching Kuuga and Den-O (I'm not even halfway through either of them.) Currently, I'm watching Fourze as it's aired, just finished Blade, and am starting to watch Den-O again.

And of course, I'd known about Kamen Rider ever since TJOmega's Dark Kabuto review, but at that point was still ignorant to ways to watch videos besides streaming.

EDIT: Wait, no, that's a lie, I'd seen a Dragon Knight promo on TV and had the obligatory "WTF Power Rangers?" reaction beforehand.

my first was Den-O and I really enjoyed that :) I've always been aware of the Kamen Rider franchise but never gave too much thought into actually watching any of it. But thanks to Chris (Vangelus) I dove into that rabbit hole and have been there since :p

Kamen Rider W was my first, been hooked from there.
Gone on to watch Kabuto, Decade, Kiva, Blade, OOO, I'm watching Faiz & Fourze now.
Tried to watch Hibiki, only made it 3 eps before giving up.

Double.

Still my favorite Rider series thus far.
