Almost, CS is dependent on it's .fgd file. And that hasn't been officially updated for ages. CS has some specific stuff, Bombzones, Hostages and that sort of thing that only relate to CS maps. And the entities are similar, The CS .fgd incorperates many of the HL entities, but adds CS specific stuff. So Yeah, basically CS tutorials are the same. CS Sites normally post CS specific stuff, that deal with their unique entities, and let sites like this deal with the basics of Mapping.
