90% of Kamen Rider episodes have one of the main characters ask "Daijobu?" to the victim of the week, and roughly 50% have them shout "Urasenai!" at the villains. That concludes your "Learn Japanese with Tokusatsu" lessons.

But yeah, having checked, Genm-Corp at least seems to consistently go for "Nee-Chan" -> "Sara".

Think we all watched the same subs. The Subbers left out the normal pronouns, you could still hear them in the dialogue opting instead for their actual names. Incase of the sister we wouldn't even know her name otherwise.

Watched the episode. In general, I liked it, although, compared to the previous ones, it seemed a little uninformative. That is, we know only a little more than Cave, but hopefully all the secrets will be cleared up in the future (and preferably not as quickly as last year). But the episode paid a lot of attention to the action, which is very cool. I absolutely love Geats' fighting style (although, as usual with Ryders, he ignores the fact that firearms are meant for ranged combat). And the aggressive combat of Buffa is not bad at all. Also, the deaths of civilians and Ryder are shown very cruelly.

As for Ace's character, I'm not a fan of this type, but so far it works. I like his relaxation and the way he sometimes seems to forget where he is and what he is doing. In general, as long as he talks less about his coolness and shows it more, everything is OK for me.

And some theories/questions:
1) Before going on a mission, Ace talked to the game manager. And at the end he appeared in a very similar outfit, only black, not white. Is this a hint that the manager was the winner of the last game?
2) Buffa works as a builder before getting Desire Driver. Given that this is already happening in the world Geats created, can hard work be a mockery of the main competitor?
3) Will we see a schoolgirl and a housewife shown at the end of the episode as riders?
4) Also, I'm wondering if there will be an analogue of Hiro Eiji, that is, a person without desires, in the show.

Yeah, these are the subs I watched and that's how they handled it. I've actually always disliked translating "Nee-chan" or "Onii-chan" into names instead of "sis" and "bro" for family or "miss" and "mister" from kids to friendly adults. This is the first time I can remember not catching it in the dialogue and the subtitles actively throwing me, though.

Either that or Someone whose desires to end the DGP entirely

I was not looking forward to Kamen Rider Fortnite...

But after watching this debut Episode, I'm actually invested!

Okay, maybe that's too strong a word, but I am intrigued, nonetheless.

So, I like how Keiwa feels like the protagonist (almost reminds me of Build's debut in a funny way), and I do like the way it's done here. One main reason is our protagonist Ukiyo, it's been a while since we had a cocky hotshot for a protagonist, but the fact that right out the gate moving into the next episode, he's already living the rich life as a boss, now that's some Tsukasa vibes, and also those words from the trailer makes sense now.

I loved the cinematography and just about everything we got from the Riders, loving Geats and his tail scarf and Buffa with his dreadlocks and coattail, and the Voices for the equipment is magnificent, already some of my favorite batch of merch. And Geat's bike, love how it's a kitsune as well, and even if this is probably the only time we see it, it sure got a lot done in its run.

I like Keiwa. I knew he was going to say World Peace right when they asked him that question. But I like how he's Haruka/OniSister and Tsuyoshi/KijiBrother in one, I'm interested in seeing more of the other characters, but I liked the Polar Bear guy for what little we saw of him.

What I'm assuming is the opening is... Not my favorite. But I'll wait for the actual opening and song to be released before I make my judgement, but from I could make out is that it's like LiveXDevil but not as cool (You can't beat the Pillar Man Theme). Again, I'll wait a bit, but for now, not the best first impression.

I'm also loving the slightly more serious tone, not as much goofy shenanigans as the previous shows, not that I had anything against humor, but it was nice to go back to (almost) early Heisei Rider in tone. Overall, I'm intrigued, and I hope they can keep strong with this series!

Next Episode: Let the Games Begin again!

This was a cool/interesting start. I could be very into this show!

People keep comparing it to Fortnite and Battle Royales and such, but with being given missions and scoring points it's more like The World Ends with You which I also like. Even the barbed wire barrier thing between Keiwa and his sister is straight from TWEWY.

I still love the Hell out of Geats' costume. Buffa's is also really cool. Very Chaos Space Marine looking.

I look forward to watching more of this. It's been a while since I've been watching the current Rider, Sentai and Ultra. I don't mind it though!

I believe somewhere it was said that the inspirations were, Fortnite, Apex, Kaiji and Squid Games.
