Yeah, what I'm trying to say is I like "gamey" games too, but I prefer the ones that have a better or more suitable or more consistent style/feel. I have nothing against games that have a "childish" style. I mean I love the original SNES Yoshi's Island. That game was built with a solid vision. But to me it really feels like Halo is trying to be cool, while at the same time being completely silly.
It really reminds me of seeing ads in the theater for Zelda 64 that had all this orchestrated music and made it look like some dramatic fantasy epic. Then you played the game and it had honky-tonk music, freakish transvestite fairies, an owl that wouldn't shut up.
Now with Zelda, I don't think Nintendo was trying to make it a huge serious epic. Its the marketing department that threw that idea out there. But with Halo, I get the impression (based on the way the music is written, and how they try to deliver the story) that they wanted it to feel like a big budget hollywood movie in a way. I feel like that really jives a bit with the actual gameplay, but moreso, the visual style and annoying sound effects.
But again, everyone has their own taste.
