Tedious, shallow combat that is also broken. When in combat, you have to wind up a swing which takes too long as by the time you're about the enemy has already gotten a hit on you. The broken part comes from the counters which if you do it right you'll enter a QTE which can instantly kill enemies.
The balancing is terrible. Most of the weapons take several hits to kill enemies, you can acquire a gun which can insta-kills enemies, and the fact that you don't really need weapons. If you go into combat with no weapons you'll come to find out that Tapp can punch much faster, do more damage, and this attack can stunlock enemies. This includes the Pigman boss fight.
No replay value.
Repetitive and, at times, frustrating puzzles. Most of time you'll be solving one of three puzzles: powering fuse boxes, connecting rotating gears, and aligning steam valves.
It's not even that scary.
Horrendous lighting. The game is so dark and the lighting is so bad that you'll most likely end up getting killed by a shotgun tripwire all because you can't see the wiring itself.
The game tries so desperately to make it out that Tapp is a bad person with Jigsaw criticizing Tapp for obessessing over him and claiming that he couldn't have killed his partner because he walked into a trap (a trap that he made). This extends even to the people that you save as they all blame Tapp for their reasoning of being caught up in Jigsaw's traps instead of the crazed serial killer that put them there to begin with.
Both endings, truth, and freedom, are absolutely terrible and depressing, and also insulting as players persevered through the entire game, only to find out it was all for nothing.
Mediocre graphics and pretty bland environments that are constantly recycled despite using the Unreal Engine 3.
Bad QTEs, especially on the PS3 version, due to using the Sixaxis feature.
Very easy to beat, unless if you play it on "Insane".
Decent music and sound design.
Good voice acting, with Tobin Bell reprising his role as the Jigsaw Killer.
The story is pretty alright, as fans of the films will definitely enjoy the story.
It was a pretty neat idea, and could have been better if it was more polished.
Saw received very mixed reviews from critics, with Metacritic scores of 59 for the PlayStation 3 and Xbox 360 versions, and 55 for the PC version. One negative review by Edge Magazine, in particular, quotes "To an industrious, moralizing serial killer, Saw would seem an apt punishment for a life wasted on video games.", giving the game a score of 4/10.
Konami hoped that this game would bring to a franchise as a spiritual successor of their other franchise, Silent Hill. However, only one sequel was made, which did even worse, and it never continued.
