orcishgamer: Dunno, I have a lot of GOGs (I would guess somewhere around 40%) and they only "weigh" around 150GB. I'd bet you could fit the whole thing on 1 TB or 1.5 TB at the worst.
Cool :)
I've been waffling about 1 or 2 TB upgrade. Using the Montgomery Scott formula, if I'm presently using a third of 1 TB, then I'll need 1.25, but the extra wiggle room wouldn't be amiss. Just wanted to know if there was a rough guesstimate.
I won't be buying the whole collection (sorry GOG Guys, I just don't like sports games and I suck at RTS) but I figured the whole collection would give me an idea for anything I'd want for the next 3-5 years.
Thanks Everyone. You've been entertaining and informative :)
