Yes the jrpg is definitely a subset of rpgs. If you noticed my list, I didnt list any of the hack and slash rpg (diablo, baldur's gate, champions of norrath, etc) nor did I mention any of the tactical rpgs (ff tactics, ogre battle, ultima exodus, etc) plus the beginner jrpgs (final fantasy mystic quest, ghost lion, etc) and there is another kind of rpg that is sort of adventure rpg (Ys, Valkyrie profile, Elder scrolls). There is another type that I basically call pen&paper rpg (Swords and serpents, the AD&D games, etc). They are all differently played types. I love the hack and slack type cause most of them are multi player and thats what me and my buddy do when we get together. I do not like the tactical rpgs as they are so slow and boring for me. Beginner jrpgs are really short and linear. The battles are all predictable and they help you through the game. They dont hold much replay value imo. Adventure rpgs have their moments. While I consider Ys one of my favorite lines of games of all time, I really did not enjoy Valkyrie profile. Same thing with the pen&paper. I actually am one of the few people that probably really enjoyed Swords and Serpents. Hated the AD&D games though. Its just a personal preference. I will 95% of the time however prefer the jrpg to any other of the subsets. Its what I have played for so long and what I revert back to everytime. If you are a rpg fan in general I do suggest that you give all the subsets a try. It could help you decide which you want to focus on.
