I'm downloading it now, good thing i have fios, this is a big one
EDIT: Just finished playing it, the water effects are amazing! I am definitely buying this one.
LOL I wish I had a connection fast enough to download a likely 2GB demo just to return an hour later to the forums to post my IMPRESSIONS on it.
But alas, I don't, anyhow, I can't wait until the Bioshock demo is released for PC (if its released before the release date, otherwise I'll just skip right straight to the full game).
