I've kinda fell into a stopping point with the game. The fact that you can be attacked at any time while training from enemies, the insane rate of how to get demons into your party, the fact that there isn't any armor, the fact that you can't have all of the god damn spells and that enemies have twice the spell range over you, and finally the fact that 'demon party abilities' (like Jack Frost's ability to power up if a Pyro Jack is in the party) ONLY applies to a regular, normal party and NOT the demons you have with you.
The rate you die in that game because of the 'all-agro rule' is insane. Because the symbol to the left indicates if the demon can be caught or note and NOT if they're agro, there's no other sign that they can be agro, so you literally have to assume that they all are, and after a certain point it becomes true. Before I found out that demon party abilities don't work like I thought they did, I was hunting for a Pyro Jack. Every single time I went out into the field to get one, 3 others would pile on me and my demon. Hell, it starts even earlier with the Inugami and the Cu Siths. Every time I went around the area that a couple were at, they'd magically spot me from god-knows-where and they'd chase me down. A very common story I've heard is how people have died at the hands of 3-5 demons because of the [tornado fang]ing all-agro rule. Lastly, the spell system is messed up. A common strategy that I know most Shin Megami players will have is to have at least one ally know every single offense spell type of a certain level (like all of the 1st, 2nd, or 3rd level spells). This game throws that out the window since the character you play as can't do that. You can have up to, what, 2 of a spell of a particular rank? And several times different elements show up on the same rank, so now you have to rely on your demon to do that. At the very least they've made it so that the demon is actually useful from it's starter level to whatever so you can kind of make up for it since finding a demon that can learn Fire, Ice, Thunder, and Force is hell.
