Well, thats actually a really good question. I have all of them. I have PH and ST on a DS and I'm playing MC on my computer. I haven't completed MC yet. Been very busy lately. I completed the firs dungeon a while ago and I havent played it since. When I have time, I can get back to it, but for now, I think it is ST. Of course I liked PH too, its just that the Ocean King's Temple is so annoying. I mean you have a limit of time to complete it and you have to do it all over again next time you visit it. But I also liked some of the characters like Oshus and Linebeck and stuff.
