I collect ever explosive I find along the way. At this point it's more about "How much can the game engine and my PC handle...". Even got a bunch of hirelings and used the vendor reset on level up to really milk some of the vendors. (This is also a great way to get some of those nastier fights in honor mode completed too...)
Just to see what would happen, in one of my evil runs, Arabella dies and for some extra spicy evil, I brought her dead body to her parents and dropped it in front of them. To my surprise... they react.
One play through I went minion master. ALL THE MINIONS. Terrible idea... each turn takes 5 years and things get clogged up real quick.
