I did encounter an issue with last night's game, though, and that was individual experience rewards. I've been handing players their XP mid-session and accepted it as a given that they'd be keeping track. I asked for an update on everyone's XP totals and got all sorts of different responses:
"I don't even have a character sheet," said one player.
"723," said the longtime friend of mine who loves to "break the system," picking apart the rules to his advantage. (This number would have been impossible to reach, as another player has attended all sessions and received the most bonus XP rewards had a grand total of 650."
"How much did we get for the first game? I forgot," said a newer player.
And so on.
I think from now on I'm going to just track player experience on my end and update them when they've earned enough to go up a level. It's a simple matter of keeping an Excel worksheet open during our game and updating their totals as I hand out rewards. Since we play strictly online games, this shouldn't be an issue.
I think this is the best way to handle tracking XP for a group of mathematically-challenged (and occasionally mischievous) players without asking them to shoulder the load of updating a shared document on our group's Facebook page or anything like that.
