The Unofficial Patch is not really a mod, but while the default basic patch fixes multiple bugs and restores only little unused content that has no impact on gameplay, the optional plus patch adds further improvements and restores a lot of hidden content, including new quests and a new map.

Exactly what AmericanCrime said: "AN essential Bloodlines patch/mod. It fixes almost everything inherently wrong with the vanilla game and aims to enhance the experience as well by restoring content. Highly Recommended!!!!!" This is the TRUE patch for any loyal fan of the game. There is absolutely no reason to not use this patch over any other patch, that claims to be, 'official'. All the mods for the game, use this patch as their foundation & regularly update to work alongside this masterpiece…
