You will love DD!!!
My first words about DD was: "Oh boy!! Blizzard is gonna be so in @)#*($@# if this company goes big!!!"
A lot of people say that BD is not as good as DD (sadly i agree), but since i have both.... i play both, and i love both...
Hint: if you find DD too easy (i doubt you will find the orc areas easy) DONT use scorpion traps... they will make it a walkthrough..... but they LOVELY when you in over your head somewhere....
