Why does everyone hate on ODST so much? This is for best campaign, and ODST totally had that.

The first 3 Halo games were relatively straightforward FPS games...

Never played it. Halo 3 was the only one I had finished before.

I liked ODST very much. Good story with nice contrast between feelings of loneliness and lively action, no Flood and good level design except Data Hive mission. Bungie's level design was a bit hit 'n miss throughout the series imo.

I played them all recently and i liked Halo 4 the most campaign-wise followed by Halo Reach

If you enjoyed the rest of the series, Reach is a must play.

Would love to say 2, but it gets halved by that horrible, horrible cliffhanger at the end. So I'm going to say Halo 1.

All you people saying Halo: Reach are breaking my heart. You guys should be embarrased!

What's wrong with Reach?

Halo 4

You mean aside from the bland and unrelatable characters, that are mostly cookie-cutter and completely underdeveloped and people often praise them because how cool their armor look (because basically that's their only virtue)? Aside from the lack of any tension whatsoever considering the game itself spoils its prequel-ish surprise right at the beginning of the game? Aside from the incredibly disjointed gameplay structure, which totally gives the impression that they designed the maps first and then looked for any cheap way for the narrative to put it all together? Aside from the Cutscene Incompetence our heroes show over and over and over again? Aside from the shallow plot holes (or plot devices if you wish to look at them like that) that fill the game, like Jorge throwing us from space to Reach, and not only not killing ourselves in the process but actually landing us almost right where we wanted to be (and before you mention Halo 3, remember, Master Chief used a spaceship to penetrate Earth's mesosphere and due to the impact on the ground he entered a comma)? Aside from the non-memorable OST? Aside from being the easiest Halo game, even on Legendary?

I don't know.

Plot holes, weak characters, and absurd character survivability are all practically givens when it comes to AAA gaming, I honestly don't even notice them any more. XD

I thought the OST was awesome, and I didn't find it too easy. (And easiness is not a flaw to me anyway)

Doesn't mean I have to like it. Especially when the other entries on the franchise prior to this one weren't as bad as this one with these flaws. :/
