Yes
yes.
Mothership Zeta is not coming out on CD, however, it will be packaged with the Fallout 3 GOTY edition which comes out in the fall of 2009. The GOTY edition will include Fallout 3 and all DLC in one package.
no even if you install the goty edition of fallout the disc will still be needed to play them.
You have to but the PC version of Fallout 3 from a store such as Walmart, Gamestop or any other store that would sell the games. If you get the regular version of Fallout 3 you would have to buy each expansion pack for your computer and it would just be easier to purchase it in the Fallout 3: Game Of The Year Edition (GOTY). I hope this helped any if anymore Questions regarding certain parts of the game post something on my wall.
Yes, you can install Fallout 3 PC mods from Fallout Nexus onto the PS3. For a tutorial, see: http://fallout-mods.blogspot.com/2010/11/fallout-3-mods-for-pc-on-ps3.html
there are no PC mods for Fallout 3 on PS3. Why do think they call it Personal Computer
No the GOTY Edition includes them. Here's a quote from related link "The Game of the Year Edition, which includes the original Fallout 3 game as well as all 5 of the downloadable content packs, was released on October 13, 2009 in North America and October 16, 2009 in Europe"
Fallout 3 PlatformsFallout 3 is available for the PC, Xbox 360 and PlayStation 3.
Fallout 3 GOTY Edition takes up about 8GB. While Fallout 3 itself is about 6GB. I suggest you have at least ~20GB free on your HDD at all times. Otherwise your overall computer performance will take a very heavy hit.
The Fallout 3 GOTY edition is basically the normal edition with the downloadable content. I'm pretty sure you have the option to omit and add DLC's, so you should be able to add the extra content with the installer, that is as long as both your version and the GOTY versions are the same (not 100% sure about this). You can patch the game after all is installed and it should work fine.
Fallout 3 can be played on the PlayStation 3, the XBox 360, and the PC.
