Why I prefer Halo 3 to Halo Reach

ill say it now, i do not dislike reach. Reach is TOTALY FRICKIN AWESOME, but i prefer Halo 3, thats all.
Anyway, time to get to the "why" part.
Halo 3's campaign. nuff said.
lol jokes, thats not enough. Halo 3's campaign, to me, is just astounding. While reach is amazing, 3 gives me the urge to travel into space, find some giant monkeys with hammers, and fill them with lead. Then theres the music. My GAWD!
anyone whos played this game knows that halo 3 had an unbelivably EPIC sountrack. Now, reach did as well... but reach didn't have this

exactly.
now, reach's soundtrack was also, muoi fantastico, to me it was just not as good as halo 3's.

Multiplayer.
personally, im not much of a multiplayer deathmatch kind of person. Im the kind of gamer who likes doing co-op stuffs. Halo 3 has a co-op campaign. So does reach. But does reach let player 2 be the Arbiter?
No. Not really.
another thing. who would you rather have driving/gunning on the final mission? an A.I?
Or your buddy in elite form?
(or sgt johnson).

Halo 3's traditional multiplayer. well, in the case of multiplayer match making, i prefer Halo reach. seeing as its far easier to defend yourself in reach, what with armor abilities and whatnot, i prefer it.
i just prefer the Halo 3 campaign, music and co-op.
