Ok, so this may sound noobish but it's important to me. I have yet to play a Shin Megami Tensei game, though they all sound like games I'd enjoy very much. Given all the different series' this encompasses, plus all the games in said series' I have to know if the individual series' follow storylines through their games or if they all interconnect, or if like all the Final Fantasies without a "-2" in it, they're all their own separate entity with nothing story-wise connecting them? So basically do any of the games follow a progression, or are they all different stories and if they do interconnect, how so? This is vital for me to know before investing in any of these games. Any help is much appreciated.
