My story with this game and restarts:
1st - Normal/Classic. Got to chapter ~3 and I was getting murdered, thought it was too hard, so I restarted...
2nd - Normal/Casual - Make it chapter ~8 this time, and now that I get a grip of the mechanics of the game, I found it way too easy on casual. So I restarted...
3rd - Normal/Classic... Made it all the way to Chapter ~13... then I realized that I power leveled and the game was way too easy. I wasn't using any strategy at all in battles, other than bumrush everyone. That wasn't what I wanted to play the game for. So I restarted...
4th - Hard/Casual... Made it to Chapter ~4, I was playing very strategic and careful, then I realized... oh if anyone dies they can just come back. lol, this is too easy! So I tried again...
5TH - HARD/CLASSIC.... Made it to Chapter ~6 last night. Seems like the right balance for me of challenging enough without being punishing. I've had to restart a few times for deaths, but mostly I'm letting shit play out. I let the Axe/Fighter dude, die when he dies. I'm pretty much setting the rule if more than one dude dies, I'm quit. But I also have a small list of characters that I will not allow to die.
So there ya go. 25 hours on the Playlog, and only on chapter 6. LOL Even with all the restarts, I am REALLY enjoying the game on a whole. Now I know not to powergrind too much to ruin the difficulty.
