With the amount of time it takes for the average 100 pt game to play coming in well over an hour (90 minutes) I'm thinking that it is not the ideal for the tournament setting. Would 70 points be more in line with being able to complete in a 60 minute game? 60 minutes is a reasonable amount of time for tournament rounds to last, with a swiss round tournament going a minimum of 3 rounds, just over 3 hours is much easier to accommodate than just under 5 hours with a potential for a fourth added round easier to swallow in the 1 hour format.
Does the game still have the depth at 70 points to make for an interesting tournament?
