The Unofficial Fallout 2 Patch 1.02+ fixes over a thousand bugs that were still left in Fallout 2 after its final patch, with complete saved game compatibility with v1.02.
The Restoration Project's more ambitious goals is to restore 'missing' content that was incomplete or pulled from the final game, including locations, quests and characters. It also comes bundled with the mod that adds high resolution support by 'Mash.'
There's no need to install 1.02+ if you use the Restoration Project, as its fixes are already included. Thanks to No Mutants Allowed for the heads-up.
