I've been playing Skies of Arcadia, which I got for Christmas. I'm loving the game so far! It's basically your typical JRPG, but set in a very unique world of air pirates and floating islands. I really like the Discoveries sidequest thing, flying around the world looking for special hidden locations. I tend to want to explore worlds in JRPGs very thoroughly, just to see what kind of things I can find, so having a mechanic built around that idea is very cool!
I also really like the characters, my favorite being Drachma, the grizzly old sky captain based off of Captain Ahab. Whenever there's an older party member in a JRPG, they always tend to be my favorite character. I'm not really sure why that is, but characters such as Strago from FFVI and Cid from FFVII (who isn't really very old, but the game made him seem that way) always seem so much more interesting to me than the younger protagonists. Also, Moby Dick happens to be my favorite book, so any reference to it gets me all excited.
And so my quest to play all of the awesome Dreamcast games that I missed out on continues!
