How does everyone feel about awarding xp durng game play. My group only meets onve very 1-2 month but we usually play for 8-12 hours when we do meet. Given the length of the sessions I am toying with the idea of awarding xp during play. Normally we will take a break for lunch and another for dinner so these would be obvious starting points to award the xp.
I am thinking a base xp rate of 5 point/ hr of play with bonuses being given for acomplishing goals or exceptionally clever ideas.
What im looking for opinions on is wether I should:
1)award xp at lunch, dinner, and then at the end. 2) award xp every hour to two. 3) wait untill the end of the session. What has your experience been with long sessions and awarding xp?
