Do you ever think to yourself "Boy! I really wish there was a game that'd really show how much I hate myself. A game that made Call of Duty look like something worth while. A game that let me experience what it's like to slowly rot from the inside out". Well if you have you're in luck! Valve released such a thing back in 2004, and it's still producing all these wonderful effects, and more!
Counter Strike: Source is the kind of game you'd see at Gamestop for $0.99 and think "Hell, it's a First-Person Shooter! It can't be that bad" but then when you get home and pop it in you figure becoming an alcoholic would be a better use of your money. Now don't get me wrong, this game isn't ALL bad, no, no. The mods for this game are actually quite fun, and the "Mini-Game" servers people make are even better. But if you're looking for a creative, fun to play First-Person shooter, you'd be better off playing Call of Duty or, I dunno, Brink.
In the end, the only reaon(s) to consider this game is because:

A: It's one of the first games Steam suggests.
B: It only suggests it because it also suggests Garry's Mod
C: You need this game for textures in Garry's Mod.

You need this game for Garry's Mod. Garry's Mod is the only reason anyone actually has this game, and you will not convince me otherwise.

I love German servers.

Fun-fact: I'm literally banned from every German server in the server list because i shouted "Heil Hitler!" or "Gas the Jews!" too much.

Ahh CS:Source.One of my personal faves ever since I was a kid.First time I played it was around 2005 but didn't like it that much mostly because everyone was still playing 1.6 which was at that time at least in my country at the peak of its glory.Neverless all of that this one still holds a special place in my heart.Playing many surf maps,zombie maps,deathruns with friends and many more.The body physics were the biggest attraction to CS:S for me.Source's graphics at that time we're insane and people were surprised with it.Compared to CS:GO today it's very underrated but what can you do,people change through the years and so does their taste.As I said Source holds a very special place because of many memories I have of it.It already has enough reviews but this one is written purely for respect for this game.Thanks for the memories Valve.
Final verdict 10/10 - Extremely recommended
