Decided to try CS Source after playing some CS:GO and Source is pretty good as well. You can have alot of fun of the community servers and its awesome to see the changes in some of the maps.

If you've playing CS:GO you should check out source.

Как только появилась эта игра. Она снесла многим головы, в том числе и мне. Я вечно в нее играл, и играю. Оптимизирована. Сбалансированная. Есть небольшие недочеты, но я думаю никто не обращает внимание на них. Она не умрет, как и CS 1.6.

A timeless classic, CS:S has aged well compared to other classic valve games. The mechanics are simple and comparable with it's successor, CS:GO. One thing that confused me going back from GO was the differences in the map layout (the visual differences also confused me slightly). One notable example was the fact that you cant jump to A-Short from Xbox in de_dust2. Other than this however, I found the game very enjoyable. If I had to make a complaint it would be that it is hard to know when an enemy died with a headshot or a bodyshot. CS:GO has implemented a system where if you headshot an enemy a special sound and visual effect are triggered, making headshot kills obvious and very satisfying. However, this does not exist in CS:S, leading me to have to constantly look at the killfeed in order to know if my kill was a headshot or not.

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

One of gaming's rarest phenomenon. CS: Source (and it's predecessors) somehow found the balance between competitive and fun. The downright silly and super serious. Technical and instinctual.
The ability to allow your players to expand upon the original game almost limitlessly. Customization and depth is everywhere. From maps, models, skins, admin commands, sprays, communication, server types, etc. The commands, binds, scripts even the hacks can all be impressive.

Servers have been around for years and some since the beginning. Servers you can call your second home, a place where everyone knows your name. A great game to meet new people and find friends.

You'll actually improve you K/D ratio depending on how drunk you are (Drunken Boxing/Zui Quan martial art equivalent).

How developers should treat the players. Give them the game and development tools. Something to start with as they explore to their imaginations limits.

The type of game you wish others followed in it's example.

One of the last great games made by Valve before they began to go downhill... Unpopular Opinion I know, but the company has been all over the place developing and experimenting in things that aren't what made them so great in the first place. Dota 2's Arcade is an exception to this; a step in the right direction that reminded me of the old days.

Overall this game is still alive and a home to many still to this day. A refuge from the experimental project known as CS: Globally Offensive.

Yes, it still holds up in 2016. It has a pretty good community, and lots of mods to ♥♥♥♥ around with

Be careful though, if you plan on playing vanilla servers (no mods/no 40 person tdm) you may be better getting GO or even 1.6
