Let\'s take 2 examples of the same situation, one with Hack n\' Slash and the other without:
The situation:
A party includes players A,B and C. A and C are good friends.
A == Male
B == Female
C == Male
A has been trying to get the attention of B for a while now, but tends to be a little overprotective of her and generally likes to show off.
C is also trying to get the attention of B, but doesn\'t try to show off or be overprotective of B.
B is a strongly independent woman, and over the past few weeks has grown attracted to C and annoyed at A.
Without Hack n\' Slash:
A,B, and C find themselves in a tavern sipping ale at the same table. All of them hae had a little bit too much to drink, and C and B are smiling at each other and mostly ignoring A. This angers A and he rises from the table and leaves. C decides to follow him to see what was wrong, and perhaps talk to him about the situation with B. A sees him coming up the stairs and in a sudden pang of jealousy lurches forward and pushes C down the stairs. C lands and breaks his kneck, and dies instantly.
With Hack n\' Slash:
The party finds itself wandering the stone labyrinths, talking queitly of the dangers in these labyrinths. Suddenly the party fins itself surrounded by monsters, and start a desperate fight. A stays at B\'s side, helping her fight off monsters which she could have easily stopped on her own. C finds himself surrounded by monsters on all sides and in desperate need of help. Only A notices, and is about to help him when B pushes A out of the way for space to swing her quaterstaff. In a sudden burst of jealousy, A pretends not to see C and C ends up dead.
The Result:
The result in both cases is that A starts to feel guilty about what he did, and the story plays itself out from there.
Now, which situation would be funnest to play? The aim of RPing is to obtain as much entertainment from the dramatic situations happening in the game. As seen from this example, Hack n\' Slash served to boost the dramatic scope of the session.
