While I absolutely love Professor Layton, I have to admit that I still haven't played Miracle Mask and that I also need to get Azran Legacy. For some reason I never finished the game before that (I'm not even sure of the title), or maybe I did, but I just can't remember? x_x Anyway, I'd say I like the first game best because it was new, challenging and original/unique (as in; I had never played such a game before and I really adored the puzzles).
