I recently played through a pair of interesting Dark Souls-inspired doujin JRPGs called Black Souls and Black Souls 2. They're really good. Wide open, yet dense worlds to explore. Lots of secrets to uncover that lead to deeper secrets. They're extremely strong in terms of choices and consequences, easily on par with the top tier of WRPGs. You can kill basically any NPC you meet, but more importantly, the things you do and don't do with different characters and events consistently lead to wildly different outcomes. If some big danger is imminent and you go kill a few bosses to level up first, don't be surprised if everyone is dead when you get back. They've got a good level of challenge, but you shouldn't have to resort to grinding.

These are both made in RPG Maker by the way
Black Souls and Black Souls 2 are H games. Both allow you to disable their hentai scenes at any time. If you suspect these games might contain something offensive that would prevent you from enjoying them, they probably do. Normally if I was playing something like this I would just keep it to myself, but these are simply too good to ignore. I cannot in good conscience deprive my fellow gamers of RPGs of this level of quality.

To be clear, this screenshot is not from an H scene
The first game's setting is largely based on western fairy tales but with a heavy dose of Dark Souls flavor. The protagonist is an immortal undead with the power to consume souls, and his goal is to lift a curse on the kingdom that causes its citizens to transform into vicious demons. Most of the major enemies and allies you'll encounter will be familiar names like Joan of Arc, Snow White, and Red Riding Hood. There's quite a bit more to the game and its story than it initially lets on and you're free to pursue the truth as much or as little as you like. The combat is fairly standard JRPG stuff. You control a single protagonist but you can spend a turn summoning ally characters to help out in combat. Many Dark Souls features and mechanics are present here. You heal at bonfires, you have healing items that recharge when you rest, souls function as both EXP and currency, and each weapon comes with its own unique moveset. I'd say its biggest flaw is that its balance falls apart towards the end of the game, mostly in the player's favor. Endgame bosses are all about getting a turn or two to set up your super OHKO attack before the enemy hits you with their OHKO attack.

Told you it's a Dark Souls ripoff. Also, despite how this looks, you can wear four rings at once, you just have to scroll down to see the other three slots.
Black Souls 2 is far more ambitious than its predecessor and draws more heavily from Bloodborne. Like early on you'll encounter a Victorian-era city, and there's an insight-like mechanic, and one of the best early game weapons is essentially the saw cleaver. The first game didn't reveal its full story unless you did some digging, but Black Souls 2 takes that idea to a ridiculous level and it's easily possible to go through multiple playthroughs and still have absolutely no idea of what is going on. I recommend playing through once while keeping your SEN at or above 100, and then a second time keeping it at or below 0. For the latter, try to get it down as early as you can. After doing those you should have a good idea of what kinds of things are possible in the game and maybe you'll have a few leads on how to go for the real ending. Make sure to talk to Dodo west of the city of Lutwidge and learn her special skill as early as you can. If you're doing a low SEN run then at least briefly raise your SEN high enough to speak with her so you can pick that up. There are two English translations of Black Souls 2 floating around on the internet. You want the one that doesn't have the F95 logo slapped onto the title screen, that one is a bad machine translation.

This fight is bad news in more ways than one
If you want to buy legitimate copies, there are official English language versions of both Black Souls games for sale at dlsite for 1,650 JPY (about $15) each. Give them a shot if you're not absolutely opposed to playing H games.
