Depends on your taste, if you like both and want both there's no reason not to buy them both together, both are great games, buy and try, you can ask for refund up to two hours! See before the refund time when it can be done.

half life

counter strike definetly

Standing here
I realize
You are just like me
Trying to make history

But who's to judge
The right from wrong
When our guard is down
I think we'll both agree

That

Violence breeds violence
But in the end it has to be this way

I've carved my own path
You followed your wrath
But maybe we're both the same

The world has turned
And so many have burned
But nobody is to blame

Yet staring across this barren wasted land
I feel new life will be born
Beneath the blood stained sand
Beneath the blood stained sand
