PersonaGAF, which SMT (including Persona) games have you all played?
For myself, it's only P3/4, and I'm almost done with SMT4. I also just started Innocent Sin and acquired Nocturne, DDS, and Soul Hackers.
If it's just played, oh god...
In order-ish of release date, Megami Tensei 1 and 2 (I own boxed Famicom copies), SMT1 and 2, Majin Tensei I and II, Kyuuyaku Megami Tensei (MT1 and 2 Super Famicom remake), SMT if, Soul Hackers (Saturn and 3DS versions), Persona 1 and both 2s, Last Bible,
SMT Trading Card: Card Summoner (it's a real thing!) one of the GBA Devil Children games, SMT3 (Dante and Raidou versions), DDS1 and 2, Persona 3 and 4, Raidou 2, Devil Survivor 1 and 2, Strange Journey, SMT4, Persona 4 Arena (arcade and PS3), and last and definitely least, SMT: Imagine. I also own a sealed copy of SMT: Nine that I hope to break out one of these days once I've modded my original Xbox to be region free. (。≖ิ‿≖ิ
Only beaten a handful of those, which would be Innocent Sin, P3 and 4, DDS1 and 2, Devil Survivor 1 and 2, and SMT4, but otherwise most all of the games on that list have had decent playtime out of me. My main issue is that I didn't grow up playing RPGs in general as someone who started off pretty late on a Genesis, so my patience for some mechanics is tested with the older games, even if I can recognize that they're otherwise generally very well made games for their time. A handful like Raidou I just don't think I'll ever get into even if the setting is fantastic because the way the combat mechanics are handled just rub me the wrong way, but otherwise I wouldn't consider what I've played of the games I haven't beaten to be wastes of time.
Still really pissed it took me three hours to recruit a Gnome as my first demon in Kyuuyaku Megami Tensei though. Cheapass wanting every last macca in my meager wallet.
