In retrospect, it was really easy when I decked out my crew. But man, I had to go back and grind for Izanami and levels. It wasn't fun
I think you're talking about my post, which dealt with the opposite.
In case you didn't know, at it's core,
Persona 2: Innocent on the PSP is one of the easiest games I have ever played. I'm not exaggerating here, the enemies you fight to too little damage, fusion spells are absurdly strong, and 90% of the bosses are pushovers, it's piss easy. I don't have a penchant for doing challenges, but I actually went ahead and ignored armor altogether, and
the game was still too easy.
If you're following the spoiler-free guide on gamefaqs, you should be set. It gives you hints, contact info and other important stuff (such as how to obtain the awakened Persona, which can be missed in this game)
