I disagree in so much as the most memorable scenarios from my perspective have been those where the game came down to the last CC of the last CCPh. I would rather lose a scenario on the last CC than have a scenario end as a draw.
If the mere act of playing a scenario was enough to satisfy the fun factor (FF), then why do most players throw in the towel when the situation appears hopeless (or mathematically impossible)? Why not play on for shits and giggles? Admittedly, some do. However, most do not, especially when playing a CG. Playing on becomes a chore. My wife assigns me enough of those without volunteering for more.
A draw is almost always a unsatisfying end to a scenario.
YFFMV.
