Looking or a good SP mod

[Javyer]

I'm looking for a good SP mod for a Valve game(I have every Valve game) so I would like to hear recommendations from you, guys.

I've already played:
For HL:
Azure Sheep
Point of View
Sweet Half-Life
Scientist SLaughterhouse
The Call of Cthululu
Half-Life: Zombie Edition
Codename Gordon

For HL2:
Get a Life
Combine Destiny
R E B E L L I O N
The Citizen

For Portal:
Portal Prelude

As you can see I love SP mods and I didn't add to the list some mods that are awful

Please, say something about the mod, if it have custom skins or something about the story, things like that.

Thank you
Javyer

Portal prelude is over hyped though, its not really that good.
