You gotta love everything about this game! No excuses! The soundtrack, the gameplay, the immersive and hypnotic story; everything! But, the biggest positive quality of all: the nostalgia factor! Or, at least, for me.

Not the best as everyone says it is, but not bad.

Pretty immersive, pretty fun, that's all there is to it.

Certainly an extraordinary Valve game, better than the original, but not worthy of too many awards. Maybe 2, at best. It seems that they sprinkled in some of the Valve charm into the game, but dumped some other stuff in there that I can't put my finger on. Tl;dr, good, but certainly not Valve's single crowning achievement.

Pretty good, even if I suck ass playing against real people.

Here's a riddle: What does the Portal series have that many other Valve games don't? The answer: aesthetic.

I would give this game five stars if it wasn't for the sequel completely upstaging it, and rightfully so.

World's best hat simulator 2022. 'Nuff said.

Don't let the "Source" part fool you, as this is not as bad as Half-Life: Source. No, this is much better; even better than any other CS.

Only better than Counter-Strike: Source in one aspect: bots. I adore how you can control bots once you die. That comes into play a lot, since I suck at playing a lof of multi-player deathmatch games and play with bots instead of real people. That, and the skin stuff, but that's about it. Everything else is what I would repeatedly dub, "not as good as Source".

Probably the worst in the Counter-Strike trilogy, but I don't mean that in a bad way. What I mean that in is a "lowest reviewed" sense, not a "one of the worst games ever made" sense. Overall, it's not bad, but it isn't as good as GO, and definitely nowhere near the high ranks of Source.

Basically the same thing as my CS review, so go read that if you want my opinion on both entries, because they are virtually the same thing.

This rating may seem biased to some people, since I have a huge history of nostalgia for both L4Ds.

Just as good as the first one, just with less of a nostalgia factor.

Same as L4D and TF2, the nostalgia factor is what really makes me like this game.
