Been playing Civ3 since C3C came out. Tried Civ4 but didn't like it. Haven't tried Civ5. Favorite scenarios are WW2 Pacific and Teturkhan. Max difficulty. (Except Japan in WW2 - Just can't win that one on max...)
Kinda funny... the
only time I've been able to win on Sid difficulty is playing Japan in WWII. And I ended up winning it pretty lopsidedly, too, with a final score of 40,910 to 10,045. Otherwise, though, I'm hopeless on Sid.
My strategy was basically blitzkrieg. In particular, I targeted the Dutch heavily due to their weak initial defences and wealth of victory points. Also swiped several American islands early, in both cases with a bias towards VPLs.
I took coastal China as well as the British lands in Burma and Malaysia/Singapore to establish a railroad from Korea to Singapore for quick reinforcement - new troops in Japan could reach parts of Borneo, Sumatra, or Java in one turn. But I ignored interior China, as the only remaining VPL in Chunking was not worth the losses required to take it. On the last turned I reached Australia, although I won before I could take any cities.
I think British Burma was as much about stopping their ability to airlift in planes and troops as anything. Once it was taken, Britain was taken care of, China was a paper tiger, America was across the ocean, and the Dutch were weak - even on Sid the AIs could only slow my advance, and not threaten me. Although they did remain at about 50% on the power graph, so if the game had gone to 1946 it may have become interesting.
