Nostalgic feelings aside, i just don't get it.
Now that i've finished both to refresh my memory (i finished CE to have a solid opinion on the game, and because i am a fan of the lore) i just cannot understand why people love CE's campaign, and think Halo 2's campaign is inferior, or downright sucks.
CE is crippled with an unfathomable amount of painfully repetitive level design and an insane amount of repetitiveness with the enemies. There is absolutely no excuse here, and i'm not just talking about the Library. It got so ridiculous at one point, that i was moving foward through the same corridor and the same room design for at least an hour, fighting the same, exact enemies. Over and over.
Halo 2 completely fixed that, offering so much more variety with its interesting, vibrant level design.
CE's vehicle controls were, to put it bluntly, horrible. Halo 2's vehicles control far more better, it was a very welcome improvement.
Now the gun in CE is, hands down, better than the gun in 2, but everything els is great, there's a decent adition of more weapons around this time, and they all feel solid, love the gunplay. Playing as the Arbitrer was awesome, personally. That blade was excellent wen dealing with the Flood, and stealthing my way wile dominating the enemies was entertaining as hell. And i loved the fact that i got to learn more about the lore, the universe and about the Covenant.
What, is it the cliffhanger ending? That thing is completely irrelevant now, thanks to all the sequels & the comic book.
Halo 2 remains my favorite campaign in the entire series. And, to me, it just crushes CE's campaign, tenfold, in every conceivable way.
