I love the Atelier Series, but have collected tons of other series on my list to someday play through (like Xenosaga, Wild Arms, Artonelico?, Suikoden (when I find a disc without a glitch). I tend to play a lot of games not in series (like Radiata Stories, Okage, Skies of Arcadia, Rogue Galaxy, and so on) because it is simply easier to pick up and play for the story without being lost (like Kingdom Hearts you needed to know Chain of Memories which was on a different console and all to understand). I have hundreds of games. My plan is to play them in my retirement lol....at least I will be keeping my mind sharp.
I must say, while I truly enjoy JRPGs, I absolutely hate thier tendency to spread out titles across every concievable Japanese platform. I refuse to buy a handheld device to continue a story and it is a cheap move on the marketing department. That is one place where most WRPGs far outclass JRPGs without even trying.
