I'm currently getting my PC-Engine Duo RGB-modded and I'm wondering if anyone here can give me some recommendations for games that are rarely discussed in the West because of the language barrier.
I'm familiar with the more famous series and titles like Ys, Langrisser, Tengai Makyo, Snatcher, Tokimeki Memorial etc. of course, so I'm looking for more obscure titles (or at least obscure in the West) that are worth a play or in some way remarkable or cool-looking.
Wow, this is delightfully obscure, and I love it!
I can only speak on some RPGs - Moonlight Lady is a fun little anime style Action RPG. Nice production values on this one, and it's somewhat playable without knowledge of the language.
Blood Gear is supposedly one of the better RPGs on the system, also a bit of an action RPG, I believe? It's a mech-based RPG that also seems to have a fair deal of polish on it. Haven't gotten too far...
Gulliver Boy has a great rendition on the PCE, especially with an arcade card. Even with just a System 3.0, the cutscenes still look great!
Definitely don't forget about the port of Popful Mail, which is much more closely based off of the original PC-98(?) version, unlike the popular Sega CD version. It's still old-school Falcon bump combat, but a ton of fun.
One of the better looking RPGs on the system is Sol Moonarge. I have no idea if this is a good game, but it looks amazing! I may end up buying this just for the uniqueness of the game.
You also have some other more well-known ones, such as Xak and Emerald Dragon.
The comics/VN above look excellent. Hudson made consistently amazing games on this system, so I think you'll be good with any of those. Makes me wish I could read fluent Japanese.
