I love playing characters when I roleplay. I try to develop characters with depth and complex emotions and feelings. I prefer DM's with a more story based game and find dungeon crawling to be boring (although I do understand and accept its place in some game systems). I also prefer systems where death and/or dismemberment are a real threat (like dark heresy), those systems happen to be the few cases where I enjoy dungeon crawling. One of my favorite memories from gaming was in dark heresy. Our group was pinned down. I was playing a young brash character that had something to prove and a superiority complex. He saw a good place to take cover and help his companions spread out. So he looked at his team and confidently said, "I'm the fastest here, I'll make a break for that cover and flank these heretics. Once I have them suppressed, you move up on them and clean up what's left." He than made a break for it and had his leg blown off. The rest of the combat was the team risking their lives trying to save him. Of course, it was made easier since the enemy was distracted by his screams of agony.
