I should note that Strikers and Royal were developed at the same time, so any plot that happened in Royal is barely if not at all mentioned here. Not a real dealbreaker though.
Touching on a subject on how Japanese games trying to sell Japan to the world, Strikers are doing this at the same level as the Yakuza games. A lot of the dialogue is banging on local cuisine and tourist hotspots. These scenes will be on the nose from the view of a cultural outsider. To be fair, they're still kids on vacation, and Osaka fresh takoyaki is pretty awesome.
Oh, that's unfortunate. I was sort of hoping it took place concurrently to Royal since I really liked both counselor man and kasumi (yeah, I know they couldn't be in a sequel).
I got Osaka fresh Takoyaki when I was over there from some random guy with a foodcart. It was alright, the flavor isn't my favorite. I had to try it after all the focus on it in Yakuza 0!! My friend I was with got REALLY mad at the street vendor cause he was talking in a really exaggeratedly slow fashion (in Japanese) to us like that would make us able to understand the language and like we were total idiots (my friend was completely fluent, and I was too stupid to be helped by that, so it pissed one of us off and I didn't even notice). Great story.
