Arent all these games the same anyhoo?
I never really understood this. By this logic all Ninja Gaiden games, Devil May Cry games, Mario games, Megaman games, Zelda games, etc... are all the same.
Yes, you run through stages beating up dudes, solving puzzles, platforming and fighting bosses and then getting new powers from each defeated boss.
However in each game you get different weapons, go to different settings, fight different enemy types with different patterns. They have different stories, etc, etc... the combat engine is pretty decent these days, and the pacing/level design/boss design tends to be really good. It also tends to look freaking amazing and have good soundtracks. They're good games, though GoW3 story was balls.
