This sure does feel like one of the first JRPG's.

Dragon Quest 1 isn't something that I'd recommend people play because it's "fun" rather, it's a game you experience so you can witness the birth of this style of game firsthand. I'll give it credit for all of the features and mechanics working correctly (a lot more rare than you think for these old games) but beyond that, there isn't much to see beyond a lot of grinding. You need to already have some level of appreciation for super retro games to be willing to see it through to the end. Certainly a one-and-done for me, but I'm at the very least glad I got to experience it.
