Alright, here's a list of some of my more favorite mods that are worth downloading - you go ahead and check them out if you want to, I don't care if you don't like them. If you don't like them, don't tell me, keep it to yourself, I don't need the attention-getting bullshit posted up on here.
Anyways, here we go...
Nightmare House 2 (HL2 Ep2 Mod)
Half-Life Redux
Earth's Special Forces (HL1 Mod, if you think im talking about the source, you're an idiot for asking)
Median XL (Diablo II LoD)
Overheid (HL2, can't remember if it's Ep2 or original.)
Ruiner (Doom 3 mod)
1187: Episode One (HL2, either original or Ep2 - it's a fucking awesome mod.)
Go-Mod (Goldsrc Engine sandbox mod - aka Half-Life, etc)
There's some others, but those are the one's that I can think of at the moment. Check out some of my watch list (if you are able to do so), to check out some other mods I have listed. And remember, before even making some dumbass comment, these are good mods in my own point of view (opinion).
And I leave off with one last bit - Fuck people who think Garry's mod is a full game. You're a fucking idiot. After all, It's called a mod, a mod requires a whole other game to run it, thus is the reason why it is called Garry's "MOD". Don't be a fucking douche.
Other than that, I wouldn't pay $10 for a mod.
As most people will hear other's say:
"Fuck that shit."
Hope you enjoy some of these mods as I have enjoyed them.
PS - I don't hate Garry's Mod. I hate the fact of having to pay for a mod. I also hate the fact that people call it a 'stand-alone game'. It's retarded when someone says that type of comment.
