Update question

[matsher]

Hi Guys,

Quick question - Just got the sim and installed form disc. No probs.
I have a 384kb line (really slow) only max 48 kb per sec download speed.

STEAM immediately started downloading a +/- 490mb update. Which it did. It took 2 hours to do.

THEN - it immediately started another update of 4 gb. !!!!!! Aaaargh, it will take days to download that update.

So the question is, what is that 2nd 4 gb update for?
Its the same size of the whole game !!!!

Can I ignore it?
