That was actually my 3rd attempt at getting the ZYW. The other two would have been victories in their own right, but not 0 year. I was determined to get a ZYW.
Yes, with spore it would have been a much quicker win, so hence a higher score. I used two little tricks with my transports that i'm sure are well known to be able to use the least amount of troops as possible. Knowing that pop was gong to be an issue i took pop growth and morale bonuses but my econ suffered.
Needless to say when i won the game i was heavily in debt.
