Why do game reviewers feel they have to compare every last game to Half Life? Practially every review has some nod to Half Life...
"Yeah, the Sims: Hot Date expansion is a great game, but it's not Half Life"
"The AI in Warcraft 3 isn't quite up to scratch compared to that of the awesome marines in Half Life"
"Deer Hunter is very much like Half Life in that you have a gun. And you shoot things."
OK, so I'm taking the michael, but the point stands. Not every game in the world has to have something in common with Half Life, nor does it owe something to Half Life. Not all games were inspired by Half Life. There were good games before Half Life, and there will be good games after Half Life. It's just tedious.
Half Life was a great game. It was indeed the way of telling the story that made it. It had a lot going for it. It's still quite good fun nowadays.
It's not the best game ever though.
What is the best game ever?
Still probably Mario 3 on the NES.
