DD is similar to Ultima 7 - easier as the ones you described. And easier than Beyond Div, as you do not have to find teachers for the skill tree - you can't unlearn skills this time. You either meet requirements due to your char lvl - or find/buy books to learn magic spells. Level cap for skills/spells is 5 for all. No battlefields to level up. Average ending is by lvl 50/52 (no level cap).

Please, download the patch 1.0034 before you start. And don't use "true shot", this skill is broken. Lockpick is very important IMO and works in Div.

Far easier than Wiz 8 in controls.
