My most favorite place of all time?
Anywhere NOT in Xenogears Land. ;3
Seriously, I have quite a few favorites. I am in LOVE with Nadia's Bell on the top of Gheddon's Tower--the music is enchanting, you get to see Marle running around with a short skirt (haha XD *points, laughs), Miguel has got to be one of the hardest bosses to fight at that part of the game if you hate stat-boosting (like me), and the sunset is just AWESOME. I also like Memoria from FFIX (especially the Crystal World) and the Ancient Forest in Final Fantasy VII. Those ARE some darn hard puzzles to figure out if you play like a decent person without an internet printout in front of you. >P Oh yes, and one more place I love--Energy Nede, in Star Ocean 2. Excel was just too... blah, but Energy Nede added a whole new twist to the game (and it also added Chisato >D).
Oh yeah! The entire game of Radical Dreamers and Castlevania SotN. >P
