When I installed my game on my new computer in April, the download was 7+ hours on DSL. Since then I have experienced at least another two hours of downloads. My DSL may not be up to the cable standards, but it's still a hell of a lot faster than Dial-up. You're in for a rough ride as far as downloads go.

But because FFXI brings everyone's speed down to 56k in game, you'll be perfectly fine when you're in.
