Campaign only took about 3 hours to beat on Normal, so that was kind of a let down. Matchmaking is much better though with the vote system.
Too much over hype imho, with people going around praising Reach and saying it's the best game ever. The day after the release date I found myself more entertained playing Fallout 3 (for the 80th time) rather than playing Reach.
All around, a pretty good game which made up for their horrible abomination that is "ODST", but too over-hyped.
Oh yeah, and for heavy forgers like me who have fairly public/popular maps, the new forge is a gift from the guardians; love it.
