I use an addon for FuBAR called AllPlayed for this.

Last time i checked it had hit 87 days played across all the characters.

you have to merge the data from the other machines into the savedvariables for the addon to get it to notice the others, or you have to log into each account with the main machine to get it to work.

wish EQ2 had a modular programming interface, as I'm now running on that game instead.

Oh and costs... uhm.

6 accounts in EQ2 is 15 bucks a month. Plus the one main in WOW that i keep around, plus the DDO account. That's 8 accounts for 15 bucks a pop. Drives my girlfriend nuts.

Per hour? uhm. i average 4 hours a night, with 8 to 10 hour binges, followed by days of drought. so, let's call it 3 hours a night, every night. 21 hours a week, 5 weeks a month, 105 hours, so a buck an hour or so. not bad, really, for the level of entertainment, but not something most people would choose to do.
