I have a somewhat complicated opinion on non-cis-white-male-etc. characters in gaming and fiction. That opinion could be summarized in a few key phrases: "I prefer diversity", "I sometimes feel uncomfortable or unworthy of writing that diversity myself", "diversity is not a numeric quota I am obliged to meet", "attacking me on this topic will cause me to ignore you", and "constructive criticism is never an attack". With all that said, I took all the Modern Generation characters we have on the wiki, collected their identity indicators into a spreadsheet here (link allows comment - more on that in a second), and graphed a few of these metrics. The results are pretty unsurprising (e.g. women outnumber men 2:1 or so). Please take a look at the spreadsheet. If you (as GM, or player of a PC, or primary writer for an NPC) know better than me, leave a comment on the spreadsheet or here, and I'll update the data. There's a lot of "unknown"/"unspecified", even among some NPCs I've been writing for, and sometimes that's okay too.
