I'm going to go with Knights in the Nightmare.
You play as a wisp of a disembodied soul from a king that just passed. He suffers from memory lost so he doesn't remember much, but as the journey goes through piece by piece drops in. The wisp must rally knights and other fighters to protect the land. The story jumps back and forth between the past and present time.
Knights in the Nightmare is a turn based strategy tactics game at its core. However other genres come into play such as real time strategy and shoot em up/bullet hell. The main goal is to kill enemies in a tic tac toe fashion across the matrix board. It sounds simple enough, but there's various stages you have to understand to fully enjoy this game. Due to this the game has been overlooked. The game has its own tutorial which can take up to an hour to fully go through, so you can see why many have pass on it or overlooked it. The game does have a pretty steep learning curve, but it's really something special once you even get half of what's going on. Now I will try my best to present most of the basics. If you feel that mine was a bit unclear I will put some of the Atlus tutorial videos at the bottom.
Your main character so to speak is the wisp ( bright white light in the picture). You can easily move the wisp around the map. The wisp controls everything on the map for your team. You see that shadow outline on the picture? That's one of your knights, you simply drag the wisp into it and you can attack. There's regular attacks in which you can charge up or you can drag an item from the item bar and give it to your knight for a special attack. However you need MP and the knight needs to be able to use that weapon for special attacks to work. In order to get MP you need to kill/damage enemies, once you do they will spit out gems which you need to collect with the wisp that restores your MP. They can also drop new items and weapons. When attacking the game will show you the range in which you can attack just like any strategy turn based game.
Now your life bar is the time section. Enemies will attack your wisp by shooting out bullets and such. If you get hit by such your time will decrease, your time also decreases when you use a attack so make sure to plan ahead before touching any of your units to prevent wasting time. You can cancel attacks, but you won't regain the lost time that you used.Once your time is dropped to zero your turn is over.
Next up is the phase act. The game has two which are law and chaos. You can switch between the two by going counter clock wise . Some weapons are only allowed in certain phases, so you might have to switch back and forth to be able to use some. It is ideal to bring in an even number of weapons for each phase before you go into battle. Changing phases also changes the attack range in which your knights can attack. Skills also changes between phases, most of the time they end up doing something completely new. Different job classes also have perks if their skills are used in a certain phase. So you will be changing phases a lot of the time and all for good reasons.
At the top left corner you see 0 Hits. That area right there is the rush count system. While in each turn the number of hits will rack up there. If you hit a certain number of hits you might trigger an effect from a weapon. Each weapon has different effect at different rush count number hits. The effects from the weapons stay in put for a good bit of time.
Now you see the for victory grid on that picture? That is the kill matrix, it shows where the enemies are and the color bar is also their life meter. Once their life meter goes to zero the words KILL will appear in that space. As I said earlier you need a tic tac toe to clear the map. Now it may take a bit of time, since enemies might not land in such a way. Fear not though, because between turns on the bottom screen a slot like machine pops up that places more enemies on the map for you to get that tic tac toe. While the machine is going you can choose which enemy/ies to appear on the screen if you're quick enough that is. Eventually the matrix will get bigger and you will have more enemies to appear on the screen.
For boss fights, they don't use the kill matrix instead HP and a rage bar appears. The rage bar is simply their meter for their most powerful move. They gain meter by getting hit or using a certain skill. The rage bar will shrink the weaker the boss gets allowing him to go into rage mode much easier. Each boss has a certain item weakness if you use it on them it slashes their meter and changes how they gain meter for the rest of the match.
That's pretty much the basics, but the game gets more complex as you go along. I can't cover everything, since I'm not totally crazy. However if you are planning to try this title out I would advise to skim through at least the tutorial. There's also various other things such as recruiting characters ( which I believe are 200ish that you can get), adjusting characters' skills upgrading and merging items. Hell you can even merge two characters souls to improve one's health. (This action cannot be reversed.) The game also allows you to replay earlier maps , so if you don't have time or just want to grind you can. There's various difficulty modes, so you can adjust to what you think you can handle.
This game does have a stiff learning curve and while going further in later levels it can get quite crazy with everything that is going on. I can see why many would be turned off from it. I enjoyed this very much and it's packed with things to do. As I said earlier I'm putting some the tutorial videos here and I even found some that showed off some of the different classes.
