I (personally) believe in 100% openness with my Players, Don Turnbull of TSR UK (great bloke, sadly missed) always found that "odd" about my style of DM'ing - that I didn't fudge rolls etc
When 4th Edition came out, and practically everything is static - with little or no rolling actually done by the player - I was more than a little incensed - as it takes away a good chunk of the fun for the player.
So, this article on 'The Action Point' really REALLY amused me -
So, basically, it seems like its actually more fun to play 4th Edition like the older editions were played - odd that . . . .
