Explain the appeal of Garry's Mod please?  I'm interested since there seems to be a lot of people who RP through it.  Unfortunately, after sitting through an hour long download, I don't really understand the way things are like...made and/or done in both the single and multiplayer realms.  No clue what or how to even "play". :/

As I currently understand it, Grray's Mod is basically the same as [url=https://en.wikipedia.org/wiki/Second_Life]Second Life[/url] but with physics as a main basis for use, free to play aspects, and ragdoll effects. A lot of playing Garry's mod involves going onto servers and playing by their mods, playing FPS type games, exploring, doing weird shit, and generally messing around. Garry's Mod is used in a lot of videos for [url=https://www.youtube.com/watch?v=prI1IXk4q8k]general shenanigans[/url] and uh... [url=https://www.youtube.com/watch?v=OHxyZaZlaOs&list=PL5C93A6E9D71C2A0E]pseudo cinematic productions[/url]. For the most part, in order to get the most value out of Garry's mod you need friends, knowledge of a fun server, or a story you want to make. 
Also a lot of the appeal is the nostalgia of Half Life 2, since it uses a lot of the props and stuff from that game.

[h3]Can anyone explain the appeal of Romantic Movies and Romantic Comedies?[/h3]
I personally absolutely do not like the genre as a whole. There are certain exceptions, of course. I don't discredit an entire bunch of movies because a few aren't my cup of tea. I want to know why some people swear by them-- Why some people have seen basically everything in the genre! Why?! 
Thank you for your attention.
