A Personal Megaten Challenge

I guess I'm going to end up going down the list of top JRPG franchises and seeing where I eventually get broken. I was first introduced to this series, along with everyone else, by the original Endurance Run. In the years since then I played the various Personas 3 through 5 entries and spinoffs, and as such those will not be included in the quixotic quest. I'm not going to even try to do this in exact order, with the English language availability being all over the place for most entries in the franchise. Also, the prominence of the sub-series compared to the main series make it tricky to figure what is and isn't a mainline Megami Tensei game. I'll do what I can.
