Great feedback on the crunch = engagement question.
I'm the RP (role-player) in the term RPG. Crunch has little appeal to me...even when I'm doing the DM thing. I'm about story...
Even in the characters I create, you can see that. I'm the kind of guy that picks and "intent" for my characters and lives it to the hilt. Example - I have a burly half-orc barbarian in my 3E game. The guiding principle about this guy was he was all about hitting. Period. Every choice I made for powers, equipment, story centered around hitting - hitting harder, faster, more often. I could care less about defense and never backed down from anything. Even my choices in armor centered around - how it allowed me to hit.
As you can guess, the personality that developed around this guy was one about rash decisions and dealing with the consequences that came about from them.
Now, while I ended up having to create an excel spread sheet to help me deal with the math of all the add-ons and temporary effects - I could care less about the min/maxing of the character. So much so, that I had to run around with a cleric in my hip pocket to deal with my inability to hold onto hit points for very long.
So as you can guess, I get "engaged" by the stuff that brings the game to life for me. Like you guys have said, everyone gets engaged in a different manner, and by different things. This was very valuable information for me, and helps me cast off a few preconceived perceptions.
Thanks!!
