So here's what I thought about Halo 4 -
I've recently gotten into Halo series. I've always found the Story interesting to read but the games are boring! Halo 3 is kinda good but again I didn't care much about the story.
Even though God of War has a fairly simplistic tale the presentation keeps me hooked.
Halo 4 changes that.
I wasn't bored by the story even though its not atypical. The visuals are breathtaking. For PC gamers used to 16xAA etc it may mean a little compromise on Jagged edges but Artwork and Frame rates are superb for Console shooter. Extremely fluid. Better than Killzone on PS3, Killzone hurts my eyes, even though it has prettier artwork.
The Gun-play is awesome. The Forerunner guns are futuristic. SAW and Suppressor feel/sound really good.

The Campaign (at Normal) took me 9 Hrs or so, got all the terminals etc. It's engaging, kept me hooked all the time. There are some changes to the core game-play which IMO make the game better.
Multiplayer is Fun. Yet to try co-op.
Just to put things in perspective. Keeping SP and MP in mind.
BF3 (PC) - 9.5
(Path-breaking, gigantic maps and vehicles, weak SP campaign) - 20-25 hrs there, too many games last year November
MW3 (Xbox360) - 9/10
(run and gun and so much fun) - Levelled upto 40
Killzone (2 and 3) (PS3) - 9/10
Gorgeous artwork. But 1 time play for me.
Crysis 2 (PC) - (8.5-9)/10 "Dumbed down graphics, not worthy of PC. Plays even worse on console". Let these comments not deter you from playing a solid game. I put in more hours into MP last year than any other Shooter. (No other games at that time)
Crysis (PC) - 9.8/10
Crysis (PS3) - 8.5/10 (Solid)
Unreal Tournament 1999 - (10/10) - The BOSS game. Upbeat Music that makes you fight harder, Epic maps, Best taunt system, Great MP. Trendsetter.
UT2K4 - (9.7/10)
Halo 4 - (9.5) I wish they made this game for PC with better physics. Must Play!
