Anyone has Fallout 3 GOTY edition? Does the game require to install the main game and all the 5 download expansion packs to the hard drive? That would take like 6-7GB.

I believe there is/never was any type of install, optional or otherwise, and ign.com says content is on 1 disc with no install:

But it still gets treated likes it DLC content.

I do not have either version.

I checked the GOTY case in the store and it requires 6GB of hard drive space. That's a lot of install data.
