If TC wanted to compare Sony games to Nintendo games, it would be better if he/she compared MediEvil to Legend of Zelda: Ocarina of Time. And you don't hear much talk about MediEvil nowadays, do you? The only thing GoW accomplished was making hack 'n' slash a lot more popular. I never played the games till the end TBH, but just from seeing videos, Castlevania: Lords of Shadows does a better job than God of War would ever do in that genre (IMO, of course).
Even so, I like GoW, because I'm a fan of hack 'n' slash, but Zelda games are something else. I might be blinded by nostalgia here, but the most fun I had playing games was playing Oracle of Seasons/Ages with my cousin. And while some may say the games having been going downhill recently, one might still think there's hope for the series. When I heard ANOTHER GoW was being released (Ascension), all I could think was "What? Again?".
