Darvond: If I wasn't playing
Dragon Quest I at such a casual pace, I'd have two large beefs with it.
• As far as I can tell, there's only one place in the entire game where the game can be saved.
• A lot of the progression hinges on having magic keys. This would be fine if every town sold them, but as far as I've progressed, there's only two vendors and both are incredibly remote, logistically speaking, with one actually requiring a magic key to find in the first place.
• With how rarely I return to the lands of this game, it would help to have a log to help keep me on track, as now I've forgotten where the best (sold) armor is and don't feel like trekking across the lands to check.
You can only save in one place, but the game world isn't big enough for that to be much of a problem. Also, in the GBC version, there is a quit save feature that allows you to suspend your game anyway (though I don't remember if you can use this after killing the final boss). Also, you can return there just by throwing some wings, or by casting the Return spell. Eventually, you get a spell that prevents weak overworld encounters from occurring.
If you already have a magic key, you can buy more in the starting castle if you don't feel like travelling to a remote area.
The best buyable armors are, of course, in the two most remote towns.
