well PenguinTD Larian followed that way for some time in the past with publishers who always try to please the masses and it didnt work all that good for them so imo this is the one chance they have to do smt different something unique smt challenging and fun.

Now imo Larian wont go in extremes like Age of Decadence, who are now at least considering to do smt about game difficulty, but still look at new XCOM EU on normal is challenging and u die alot if u dont think and u have to reload sometimes if u want to get out clean otherwise your mistakes just pile up until its not possible to end the game. Some prb said that this kind of game wont reach to new generations that it wont sell but it did and not only that it brought many oldtimers back to PC.

Im pretty sure that there will be difficulty levels for DOS imo like the ones in D&D games where on easy u dont do friendly fire and u get only 3/4 of damage and so on.
