dtgreene: I've heard that the Japanese Super Famicom version is *very* different from the original, though I haven't had a chance to see it player or attempt to play it.
HIRO kun: I had totally forgotten this hidden gem. lol. Perhaps I'll play it someday.
As for the PC88 version, I moved on to these 5 towns by teleport portals, and of course, wrote these maps with a pen and a graph paper notebook. After my adventurers became level 7, I began exploring outside of the starting town, MiddleGate.
By the way, StarCraft, a localizing company, had a strange decision about the game, They translated event messages and shop descriptions into Japanese, but everything else is still in English. so this version is an amalgam of Japanese and English (the rate may be Japanese 20% and English 80%). I imagine an average Japanese kid who didn't know English at all bought this game, but couldn't figure out how to play the game, and eventually had to give up it. I guess this is one of the reasons why this game is not so popular in Japan as the previous one which was fully translated.
I do seem to remember many early Japanese arcade-ish video games, particularly those that don't have that much text, would not have any Japanese text. See, for example, Super Mario Bros. 1, as well as The Lost Levels (Super Mario Bros. 2 in Japan); as far as I can tell, there's no Japanese text in the Japanese versions (not counting Lost Levels 9-4, where some Japanese is written via the blocks in the level).
There's one Japanese game I played, Game Center CX 2, which is basically a bunch of sub-games styled after (mostly) 8-bit games of the past. And there, in the sub-games, you don't really see Japanese text, except for the adventure game (which is pretty much just text), and the RPG (which has a lot of text); those games, though, are entirely Japanese (though I think they lack Kanji).
(The first Game Center CX got released in the US under the title Retro Game Challenge; the second one did not officially get translated (I played an imported copy), though I've heard a fan translation exists.)
Going back to Might & Magic, the first game's NES port definitely upgraded the graphics (you can see enemies during battle) and added music, but it also added some bugs. There's one bug that can be used to transmute items (just look up a speedrun of this version, and not a "glitchless" or "no major glitches" one), but the one that's mainly worrying is the one involving Locust Plagues. Thing is, if one of them gets to attack:
* The attack will hit for 255 damage. (In other versions, this enemy only does 1 damage per hit, so at most 10 damage per attack since it gets 10 attacks per round; this large amount of damage is *definitely* a bug.)
* The attack will kill the unlucky party member who is targeted.
* Due to *another* bug, anybody in the party who hasn't acted this turn doesn't get to act.
* Start of the next round, the Locust Plague is faster than your party, and therefore gets to attack first.
* And, of course, it will attack and kill another party member.
* Repeat until party wipe, with there being nothing the player can do about this.
