I used to play multiple RPGs like Maplestory but that was a long time ago. You might find your answer in this Section or this one. I don't have a clue since I neither own a PS3 or an Xbox 360 so I'm rusty on gaming.
Some of the more better RPG/Adventure games on AG would be the Arcuz Series, Castaway Series, and the Hand of War games. There are others as well.
If your looking for something on a console, I'm currently playing Lord of the Rings: War in the North. It's quite good, but pretty difficult if you don't have anyone else to play with.
Haven't really played any good RPG's or Adventure games on PC in quite a few years so I cannot suggest one.
