How often do you make this journey?
How happy are the group to have to make this length of journey?
If you like calculate your average player travel time (in minutes) and divide by the number of weeks between games. This will give us what I'm calling your Weekly Travel Index (WTI)!
I game with a single group (in the UK) of up to 6 people and only two of us live in the same town. We usually try to play at one guy's house in the countryside, which gives us total travel times of about 40 minutes, 20 minutes, 30 minutes, 30 minutes and 25 minutes. We do this once every two weeks, with the very occasional weekend game.
Our WTI is 12.08 minutes. How happy are we? We're ok with it since it's only every two weeks.
Or maybe this is just daft!?
Oh and perhaps this is also interesting: What's the max travel time you and your group would accept to get your gaming fix? (Perhaps that's about what WTI you'd be happy with since most people are probably happy to travel for longer if they don't have to do it so often?) Another way of of looking at it would be: what WTI do you think would cause your group to splinter?
The max WTI I'd personally put up with is about 20 mins - there's dedication to the gaming cause!
