Very interesting responses to my question! I like that several of you even broke down "RPG" into more specific things like saying "story-driven" etc. I'm definitely the same as well when it comes to RPGs.
To your question, @mrfuji3, yeah I'm limited in my gaming interests mainly for two reasons. One, given my real-life time limits, I get to play video games only for a few hours each week. And on top of that, I'm the kind of gamer who likes to take my own sweet time through my RPGs, and will spend spend tons of time agonizing over a choice or even just deciding which of my party members should get a new piece of equipment. So I don't get to play too many games per year. And two, I came to gaming very late in my life, because as an immigrant to the US who put himself through years of grad school I was very broke for a very long time and was able to afford to buy my own computer only in 1998 at age 31.
