Our group will be starting its campaign tomorrow. We are shooting for a run that lasts as long as FFG keeps putting out support. 3+ years it seems at this point. We get together for 4 hrs and have 30 min of chatter before and after play leaving 3 hrs. of solid play time. As suggested that would be 15 xp per session. At 10 months of play time (2 months for vacations, breaks and whatnot) that is a total of 600 xp a year. After playing with a character builder, that is a LOT of growth it seems, or is that what is to be expected?
I guess the question is; What kind of growth do GMs plan on shooting for between books?
