im trying to be careful about making up plot of Syndicate game because at some point it just turns into a book instead of a game, of one thing im sure that i would want to put emphasis on and that's forms of address
yeah yeah going through Yakuza/Lads series certainly is part of the reason, but it's really cool how much information you can get just through that! and so many languages do that, in many fascinating ways, even English to some degree, and I think it would be interesting to differentiate how secondary characters interact with Protag
let's say Albrecht, a crackhead priest, man living a double lie, using very long polite forms, "Could you please?...", "Wouldn't you", this kind of stuff, but mixed up with horrible diminutives, it's not Count or Sir de Wett, or even Roderick, but Dick, Rod (make it more phallic, I'll wait). Not Master or Mister Zaleglowicz, no Feliks, but Fela (feminine), Fifi (literally the wrong name, Fifi is Philip). for some reason Albrecht calls Grandmaster Jack (but only when mentioning him to Roderick)
also this ties to the fact that I have a name for Protagonist - Sebastian. not only is it very nice, gay, saint name, but also immediately reminds me of dresy. Seba, Sebix, Bastian, Bastek - i know this guy, from my block. i feel like I don't even have to describe him.
