you'll probably get different answers from anyone you ask. Here are some thoughts I had but only because you asked.
I like to be surprised as a GM at the creativity of the players. I had encouraged the character creation rule on page 33.
Every talent has three ranks. You normally
start the game with rank 1 in each talent, but
you can choose to forgo one general talent for
starting the game with rank 2 in another.
This gave us some crazy ass beginning characters. Blood Mage Wizards that can bind demons, druids that can do amazing damage, fighters who can do horrendous damage by ignoring the armor, Death Mage wizards who can stop the beating heart of a strong foe, minstrels whos warcry removed nearly all the dice from their opponents.
Also many of the group were prepared because they had played other OSR games and knew that avoiding and encounter was a success conclusion to an encounter. A lesson DnD groups will learn if given a chance.
When I developed the pre planned things *(I do less of that now then I did at first) I found that having a WP pool for the humanoid opponents was a great equalizer. By having a warrior on the opponents side with a Rank 2 Path talent almost always made him the target as soon as I called out using it, plus the looks on the characters faces was priceless. I also found that monsters should be the same strength total as the group /2 for a strong battle, /1 for a very hard battle, x2 an impossible battle. those are only a rule of thumb, a group of whiners only have str 1, but they have no problem letting a tunnel collapse on the group if they want to kill them. I freed myself from thinking like that when they bound my first demon, now I don't nerf any longer.The random encounters also are really well done, so I am trying to mimic that style on the fly with adjustment. I also like to reskin creature codex or other games monsters so that has been a blast.
i feel that part of the problem with DnD is all the meta gaming, CR control, testing trials, and such that says as a player if I see something charge because it is a battle I can win if I'm decisive and we combat well, if we run we don't get xp or gold so never retreat, never surrender. This makes me sad...
