Well, it took me more time to play the computer game than it did for the real war to play out, but I have finally managed to finish/win a game of Gary Grigsby's monster game War in the Pacific:
I'm not sure that I'll ever play it again. Perhaps when I retire! But I prefer more focused games now, which put the player at an actual level of command. The detail is vast, absolutely vast. A fair bit can be automated, but I don't find the automation that intuitive or effective in many instances, which therefore means lots of things have to be micro-managed.
