So a somewhat lacklustre showing from the more recent poll, but with the 'Up to two hours hours per four of game time' option winning out. One poor soul is doing three hours of prep per four hours of gaming... this was along the lines of what I was having to do for my old d20 Modern 'Blue Pill' campaign, and is one of the reasons why it folded. I certainly can't be doing that these days, with my own vote going in the 'Up to 2 hours' bracket.
And now, the first point of comparison. I've raised the same poll, but with respect to 4th Edition. Let's see how the numbers pan out in the brave new world, shall we?
