I always thought of Strange Journey as SMT4.
It was. I don't really understand what got into them.
Maybe they decided to use Strange Journey as the starting point of yet another thread in the Shin Megami Tensei multiverse.
It was probably Digital Devil Saga then.
Digital Devil Saga probably.
Or the Raidou Kuzunoha (Devil Summoner) games.
I can understand why some locals would find it hard to get into them if not already into Shin Megami Tensei.
Where could I get good translations of SMT "1", "2" and "if..." ?
For "if..." you are without luck. It seems there is a translation project going on by the guys who translated 1 and 2, but I believe they are translating the IMO much inferior SNES version.
Other than that there is a translation guide / translated script, but it only covers two and a half routes.
Haven't played anything in the main canon so are they somehow interconnected?
They are: Shin Megami Tensei 2 is a direct sequel of Shin Megami Tensei's neutral ending, and Nocturne is very inderectly a sequel of Shin Megami Tensei 2.
The plotlines, however, are self contained. You will lose nothing starting by Nocturne, for example, as while there is a plotline that sheds some light over the second game's ending you will only notice it is related if you did play it beforehand, if you haven't it looks like it's own thing.
I've been playing the very first SMT for the past several days. Two things:
This game is fucking LONG
and
This game is fucking GRINDY
But I'm still having fun with it, for whatever reason.
I also played SMT: Strange Journey, that game was excellent. I think I'm going to try to get all the way through the entire series before SMT IV. Between this and Etrian Odyssey IV, I'm glad I bought a 3DS.
What the manatee said, use SLEEP rounds and give your human characters guns that hit all the enemy party, or most of it, to demolish normal encounters on AUTO.
Then, BUFU and ZIO spells always freeze and shock on SMT1. And most bosses are not immune to either, or both. Do the math.
The enemies against which those two tactics (or exploits, if you will) do not work are not going to get any easier no matter how much you grind as they use those very same tactics on you, are insanely though tanks, spam instant death, or are innately reflective.
The really badass demons that are not bosses, like those insane Orobas groups that will demolish your party on AUTO, you can just bypass by fusing or recruiting one of your own, as they will then let you go unharmed as long as it isn't full moon.
