There are a few, for me. But worlds, not exact spots. I loved DS and Celestia. I wasn't a big fan of Zafaria, and I am sort of liking Avalon. But the WORST place for me, would have to be Marleybone. Once you're past that, it's a lot better, even though the bosses get harder.
I absolutely love just standing around on the edge of the land chunks and looking at the Krokotopian skyline at the Oasis. First glance up, where the few wisps of gelatin desert cloud are congregating in a circle around the center of the sky, gently and slowly rotating, blown apart by the howling wind. Then take your eyes down, into the bottom of the sky, below the desert chunks-it fades to white, a strange mythical white of legends. I love this more than almost any other place in the game.
The other places I love are the towers with magma flowing in in Dragonspyre. The ones in the dungeons, the ones at the end, with the pulsing masses of molten rock flowing into the room.
i like a few. i like marleybone because its cool. i like avalon because everyone is cool.my personal favorite is where malistare is because is like a church and its just coll knowing your fighting malistare.
