Just curious, does anyone know what game on GOG has the largest download/install size?

witcher 2 probably. its 15.2 GB

Witcher 2, Mac version, since it's a single file of ~17GB. There are a few more huge files, but no other is that close (yet)

Hmmm, that seems to be it, my Witcher 2 install is 22GB, but it might be a bit bigger because I have a mod installed.

And what about the smallest?

Technically it's 2gb as that's how large the files are that GOG splits them to when they get too large. Or at least I think it's 2gb, it winds up being something like that. Ithink it's something like 2 per DVD. Hard to say, that would probably be like Dangerous Dave or possibly Wasteland, I think both of them would fit on a disk if not for having to include DOSBox.

Ignoring some of the Omerta DLCs, I think it's Personal Nightmare and Sword of the Samurai at 16MB. There may be a few smaller ones, but doubt it.

Edit: Dangerous Dave and Catacombs pack are at 14MB.

Edit 2: Sid Meier's Covert Action is at 13MB.

Catacombs Pack - 2nd place, 14MB :)

Along with Dangerous Dave :)

probably will be tesla effect after today.

You mean the first edit in the post you replied to? :P

@doh... Yup.

Tangent: I couldn't believe Sir, You Are Being Hunted was only 250MB when I downloaded it today.

teenagent gets third place with 15MB

Kinda reminds me of all those CD's Pandora Directive came on in the day due to those FMV's

Smallest filesizes for the installers though are for the DLCs.

DLC: Raptor and DLC: Heroes of the Fleet are at 5MB, but the biggest (smallest?) winner is DLC: Ether One Deluxe Edition Upgrade with an installer size of 0MB, since it's just extras ;)
