Actually, I
am a programmer! Are you?
I don't know what people are expecting from Civ III MP that's so exotic. All that they need to do for hot-seat (not ideal, but all you can do with a single PC), is allow a second player turn and record messages that were broadcast ("The English have completed the Pyramids.") to play back at the start of each player's turn. Setting that up is such a trivial job, that a day is probably not much of an exageration. You give control back to the player console for one Civ per turn, or for two - what's the big deal? They
should add the ability to "replay opponents turn" so you get an opportunity to see the enemy move around you. That addition would clearly take some time to do right, and would be a valuable upgrade to the Civ II hotseat model.
Good
simultaneous MP is another thing entirely, and maybe that's what they're spending all of their time on. I don't think it's even desirable! Civ is turn-based, after all.
I play all of my Civ II MP in a networked environment, via direct connection or dial-up networking. That means that players (and AIs) move in turn,
but one human could still watch the other sides move, see the broadcasts as they happened, and even take care of micromanagement tasks like setting the tax rate, moving worked tiles around, and changing construction
while the other sides are moving. That's an important time-saver, and I'm sure it's not completely trivial to set up. Still, the only part of all that which is really different from the SP game is the connection.
Civ II already has perfectly good MP. The only thing that really needed work was the modem connection, and Blizzard had a perfectly good connection interface for
Warcraft II way back when - it's not like Firaxis actually has to be creative here!
