Pros: Greatly improved graphics, free consumer supported online play, Action-packed gameplay, Years of fun.
Cons: Scores in game will be fairly low at first if new to first person shooters.
The bottom line: I have played for years and involved my family and friends. If I recommend it to them then I think this game can be great for everyone.
I have been playing many first person shooters and have been gaming for almost 10 years online. Counterstrike has impressed me and enticed me for almost 5 years since the original counterstrike came out after Half-life had been released. This game features fast pace gameplay, short rounds, a vast number of official and custom maps, several priced real-life simulated weapons. This game is for adults and children both. Me and my 3 younger brother love to all play together online and when we get the competition going it can be a fun night of gaming while the weather isn't so great.

Counterstrike: Source is an intense action-packed game that will make your adrenaline pump wildly. I don't think I have ever played a game where the action was so intense and involving. There is voice communication capabilities and you can talk to anyone from almost anywhere in the world. All you have to do is buy the game and have an internet connection, and you are ready to play away.

It takes a few times playing to really get the hang of it, but if you give it a little time you will enjoy the game more and more as you progressively improve. I have recommended this game to friends and family, and I think if someone tries this game they will love it.
