I'm a huge fan myself, I didn't know Strange journey was a successor to Noctrune though.
I got into The SMT series Persona 3 which I loved, and broke (many time over) with the satan lucifer combo attack, since lucifer had "Salvation" which recovered my MP after battle, doubling stats with trips the shrine, and power leveling at the beginning of the month. I liked the heavy story of this game.
I played through persona 2(US), 2(JP), 3, & 4
Still playing, Strange journey, Noctrune, persona (psp), persona 3 (psp).
I have not played Digital devil, or devil summoner series.
I love the megaten wiki.
Also Watched some of the anime trinity soul. If you haven't seen it you Persona 4 is getting an anime adaption too
