Nintendo

For what it's worth, I played the NES release of DQ1, and then a translation of the japan-only SNES release of DQ2 recently (I actually beat DQ2 last week) and I found DQ2 to be a much better game than DQ1 overall. DQ1 was... interesting, but it was very much a game that did not respect the player's time in the least, to the point of expecting the player to fight literally hundreds of battles in order to grind up enough money and experience to afford the gear. The most charitable thing I can say about it is that the battle system was so rudimentary and so grindy that the gameplay felt more like it was focused on resource management--there was a tension in deciding whether you could afford to take another fight, or if you needed to return to town and spend money sleeping at an inn to heal (setting your grind back at least 1-2 fights with how piddly gold and XP drops were), optimizing efficiency in spending your MP to heal vs. the risk of dying to the next monster, etc.

DQ2 meanwhile was a much more robust and much less grindy game--the simple addition of multiple party members and multiple enemies in a single battle meant that your gold and XP gains were multiplied over the first game. While it still demanded grinding, it was much more reasonable about it, and it felt much more like a "modern" JRPG like you're used to seeing.
