I remember seeing a Mod before on the site that connected Baldur's Gate 1, Baldur's Gate II, ToB, plus some of the mischellaneous mods like Dark Side of the Sword Coast and the lot together into one huge game. I can't remember what it was called, and I can't seem to find it anymore. If somebody could tell me what it was and where I can find it, I'd appreciate it.

Sounds like a problematic program to me. Not all mods like each other, unless if the creator knew what mods to add and in what order for them to be installed in your comp. :p

I would suggest installing them one by one insted, I'm sure any mods you need can be found here:

Baldur's Gate I + TotSC (http://www.sorcerers.net/Games/BG/index.php)
Baldur's Gate II + ToB (http://www.sorcerers.net/Games/BG2/index.php)

Sounds like you're looking for The Big Picture, iirc the name.

I thought it was called something like that! Thanks! Now, as soon as I figure out what the heck iirc is...

If I recall correctly (iirc). I wasn't sure of the name, so I put iirc. Sorry for the confusion.

Note that Big Picture is NOT usable with all mods.
Also Baldur's Gate Trilogy will allow you to play all the way iirc.

You can check which version of Big Picture that's needed for different mod combo's..

Thanks a lot. I'm almost through Throne of Baal as a good character, and I wanna play through as an Evil one. This will make things a lot less complicated.

EDIT: Really, I just want the mod that lets me play BG, TotSC, BGII and ToB in a row itself, not all the Dark Side stuff. It says I need the Big Picture itself before I can install the Big Picture + Trilogy + DSotSC and stuff...and frankly, I don't have the feintest idea what to install first and everything...all these mods are too confusing.

At blackwyrmlair you can download Big Picture with the other mods, and it comes with an installer that'll install everything iirc.
However you might want to check some up concerning Big Picture with someone who'd actually played it. It gave me so many complications that I gave up on it :p
