Ok, here comes the doom grunt.
Well, i see that most of people only scratched the surface of this game. Edge retrospective lacks a particular that is mentioned in the recent Left 4 Dead Review, e.g. the times zombies don't pop up from the angle. For the many moments it happens at least half the same number they don't show up. It's a matter of "participation" to the game, driven by atmosphere. There are times where you stare at a ceiling or a gap in the floor thinking the moment the trites will come out. And most of the times they don't come.
Other times you forget some of those amusing guys alive in the level. Well, i was solving the radiation barrels puzzle and i got my back scratched. Then i never relaxed again when playing it.
I think it's worth an 82% for this unusual "participation". The whole game lies on it. But is nothing revolutionary, memorable is more appropriate. The memorability is achieved through the use of technique, yet, IMHO, it's achieved. The maniac balancing of the arsenal is another point to the game: various styles of gameplay allow for various weapons in the same spot. But both the things are subjective, i admit that. It share with Half Life 2 the look for "Love it or hate it" and i don't need to specify which i love and which i hate cause it's evident (thought i don't really hate Half Life 2, it simply don't impress me to the point of saying it's a masterpiece, because i played his better, smarter predecessor).
The last real revolutions i saw are Quake 2 and Half Life 1. The progress then slowed down to a shortcoming i hope we will be able tho break open not too late.
