Well, I've had the PC version of Fallout 3 for a week now, and the first mods I'd like to install are graphics enhancing mods. I've looked around a bit, but I'm slightly confused as to what they all are/which are the best ones. All I've found are bits and pieces. Weapon mods that also seem to cover rocks, mods that cover everything but rocks...
Are there any sort of cover everything mods? Weapons, rocks, roads, armor etc. all in one single download?
As far as I know, there's nothing quite like, say, QTP3 or what have you. However, there's the Terrain Pack, which covers a fair bit of stuff, and then, yes, a bunch of other mods to cover most of the rest I guess.
Checking out Arwen's site (the Fallout section) might be worthwhile. Plenty of advice and insight, with regards to installation, load order, tweaking, etc.
You could also try browsing the category of "Models and Textures" over at Fallout3Nexus.com, and perhaps sorting it by file size (descending) or even downloads (descending)... something like that.
If you want opinions or advice about any in particular, I'm sure the folks here would be more than happy to assist.
