I'm a white American dude of primarily Irish and Scots-Irish extraction (with a little bit of German and Italian), so I'm pretty far from being classified or qualified as being Hispanic or Latino. But I do have two interesting stories regarding RPG's and Hispanic gamers.
I had a friend in High School who was two grades ahead of me, but we both were part of the school's Latin Club and often would meet at club functions (such as attending the Junior Classical League Convention in Richmond, Virginia in November of 2008). This girl was of mixed ancestry, half-Japanese and half-Latino. She identified with her Asian heritage more than her Hispanic heritage though.
However, I got her interested in tabletop RPG's, particularly Dungeons & Dragons (4e was out at the time, but I recommended she start with an older copy of 3.5 if possible) and Big Eyes Small Mouth (she was also a fan of anime like me). She seemed a little uninterested at first, but decided to try the games out anyway.
During the convention in Richmond back in 2008, my father was one of the chaperones for the school's club on this particular trip and me and him stayed at the same hotel room. We brought some D&D books, pens and notebooks, and some dice with us (specifically the 3.5 Player's Handbook). The convention had a whole segment dedicated to games in general, called "Ludi Frivoli" and the people there mostly played backgammon, various other board games and card games (I did see one group of people playing Magic), and there was even a small boffer combat gathering as well, done with pool noodles, cheap foam Nerf swords, and the like. There was an open table, so my dad and I decided to play a largely impromptu D&D one-shot and my friend decided to join us.
It was pretty cool, I played a Human Sorcerer and she was a Half-Elf Bard.
Later that school year, she graduated but we still were friends on Facebook though we don't talk much. She lives her own life (and apparently moved to somewhere in upstate New York, if Facebook is to be believed) and I live my own life here in Virginia. But I recently saw some posts of her on my Facebook feed of her posting Pathfinder memes and a picture of her at a table with a Pathfinder group.
She's now an RPG gamer and I'd like to think I helped her become one.
I also used to play in a Vampire: The Masquerade LARP with a friend of Puerto Rican background. He was a cool guy overall and again, we're still friends on Facebook, though he lives in Florida now last I heard. Guy was an awesome dude, a fellow anime fan and a great cosplayer. He was also one of the few LARP'ers in that group who was neither a Goth asshole or a Gen X burnout or both (Seriously, me and him were the only Millennials in that group at different points).
Sorry if it's a little off-topic. I just thought I'd share my own personal experiences with Hispanic gamers.
