Apparently you need to have Half-life 2 installed in order to play SourceForts. Atleast I get this weird error saying I need Half-life 2, which I don't have installed on my account at the moment.

yup you need hl2 to play sourceforts as it is a modification of it.

Do you have any other game with source sdk installed?

You only need to own HL2: DM to play SF, as long as you have downloaded the Source SDK Base it should work fine.

The Source SDK Base is a game that includes all the necessary components such as materials, models and configuration files for mods. While we overwrite a lot of them, things like the player models are taken from there to keep the size of mod downloads to a minimum.
