[Suzerain of Sheol]

Up until I was 6 years old or so, I didn't know what a video game was, and then one fateful night my favorite uncle came over with a very large bag containing in it an NES and a SNES, along with... basically every major RPG made to that point on those systems. All of which I was way too young to understand or be able to play even remotely competently, but that did not stop me. In no particular order, from recollection there was

Dragon Warrior 1,2,3,4 (back when they were called Dragon Warrior)
Final Fantasy 1,2,3 (yes yes we all know what the numbers actually are)
Ultima 3,4,5 (6 year old me did not understand the concept of NOT breaking every single virtue, alas)
Castlevania 2,3,4 (I never did like these games...)
Secret of Mana (Did this age well? It's one of the few I've never replayed as an adult)
Super Mario RPG (before I ever even knew who Mario was)
Chrono Trigger (what even needs to be said?)

And probably a large number of off-brand titles I can't remember. You could say I was spoiled for choice. I think my preference for RPGs over any other genre is a well-defined psychological study. :P
