Much like with the first game, finding the story DLC and best mods for this is fairly easy if you know where to look, but if you want a more modern looking game, I'd highly recommend picking up the Legendary Edition instead.

You should be able to find the DLC and best mods for this game if you look around enough, though I'd rather you just buy the Legendary Edition because of the gameplay improvements. Aside from that, there's a reason this was so lauded at the end of 2007.

Wish this game could be nominated for GOTY every year.
