Call me weird, but 90% of my CM time is spent altering existing scenarios or creating new ones.
Part of it is due to my chronic fatigue (late shift warehousework plus a mild heart condition) and part of it is CM being my childhood dream come true (I used to spend hours drawing stickfigure battles on elaborate terrain -- "What's wrong with this boy?" my granddad used to ask).
So when I come home too tired to think I nevertheless spend a relaxing hour or two changing scenario maps till they look 'right'.
I've changed every scenario in both CMOO and CMOB.
And I've done more than 100 scenarios from scratch such as, my own versions of the Falaise Pocket or the Hurtgen Forest, lesser known battles like the Brit commando raid on occupied Guernsey or the Polish defense of Westerplatte, Dieppe of course (I'm Canadian), allies overunning research bases like Rechlin or E. Stelle Travermunde, the Polish attacking Peenemunde, operation Felix (Gibralter), and some odd fictional battles like American airborne assaulting Carinhall (in hopes of nabbing Goring), or Skorzeny leading an attack on the Nuremburg Trial site, or even dropping in on Los Alamos (courtesy of a squadron of Junkers 390s).
In short, CM is for me a creative hobby involving research and imagination. I get a great sense of accomplishment when I complete each one.
Yet so far I've playtested very few, but will get around to them all as time goes on. (Rechlin airbase turned out to be too lopsided. All the antiaircraft weapons sited about the base made short work of allied armour. Must rethink this one.)
Note that 'After The Battle' magazine is a superb resource with both detailed maps and excellent photos for a host of obscure battles.
Anyway, just curious. Which aspect of the game do you enjoy the most? What percentage of time is devoted to creating rather than playing? Im my case 90/10. I'd be interested in finding out if I'm unique in this or if many share my approach to CM.
