6 was an interesting game. It's not very good, and I often didn't feel like I was playing Disgaea. The story is also badly laid out. It follows a pattern of "meet someone new and die" until you get everyone. Then it's "character arc and die" until you confront the villain of the game. The story kind of got interesting by the end, but by that point, you're so checked out, it doesn't matter. The postgame isn't great either, nor is the item world. There's kind of no point in playing past the main story, but I did it for some very boring interactions with the cast of the first game. I'm not playing 7 until the newest version comes to Steam. I did play the demo of 7 on my Switch, however, and it did feel more like a Disgaea, so make of that what you will.
