After reading through the various mods available I like the sound of Restoration Project, Resolution Patch and Unofficial update by Killap. There's also another unofficial update called 1.05 I think but I don't know if that's needed or not. What I want is widescreen, bug fixes and restoring planned content.
Is there a certain order I should install them with?
Killap's two patches, the restoration project and the unofficial update, supersede and include all patches and approaches before. You only need to install either the unofficial patch, which fixes only bugs & has the resolution patch or the restoration project which additional included community finished content of things left unfinished in the game by the original developers.
