Yeah, I'm gonna have to explain it to you in the most detailed way now because you're clearly not getting what Raven and the others are trying to explain to you.
Okay, you seem to have some conflict by dealing with the fact that you need Half-Life to play ESF
No HL = No ESF
Please note that this is a MODIFICATION FOR Half-Life, which means it uses Half-Life's resources to install the game. Without these resources than there's no way to install it. I'm not going to go into full detail about what exactly a MOD is because you should understand this by now.
Now don't talk about pirating here aswell. Especially infront of the forum, if you pirated HL then you don't get support. Don't lie to us by saying that 10 bucks is heaps for your country because you or your parents won't allow you to buy HL
Also I don't get what's the deal with you complaining how expensive HL is for you on the forum. That's something for your nose to stick up with Valve because we didn't make HL or Steam and we certainly can't change the price. If it's too expensive then SAVE UP some money.
Good Things Come to those who WAIT
