I've never been to Disneyland. Have never really wanted to, either, not my cup of tea. But if I ever did, and in particular wanted to go see the Twilight Zone ride Tower of Terror, now I can. And I don't need to either pay money or get off my ass. That's a win, and another win.
These are my favourite kind of HL2 mods. Utterly pointless from a gaming perspective, just really fun to watch.
