I havent been able to play Reach near as much as I've wanted to.  I've been letting my son and a group of Halo minded boys play it.  So far they have beaten the single player (and coop) 2 times, they have done plenty of firefight matches, some offline slayer, and even some forge.  The funny thing is my Son who is 10 is so interested in the story and making sure he plays it correctly he's started playing in order!  He beat Reach, then he played Halo 1.  After Halo 1 he started playing Halo 2.  Right when New Mombasa gets destroyed he saves and puts in Halo 3:ODST. Once he finished ODST he's going to finish Halo 2 and then beat Halo 3.  He gave Halo Wars a shot but it just wasnt for him.
 
After that he's going to read the books.  Now I know this sounds like I just let him run rampant and play a crazy amount of games but i dont lol!  The weather has been crap so he's been stuck inside with his friends and its actually quite alot of fun listening to all of them play.  Its also gotten him in the mood to read the books which is good.  He's already about 1/4 of the way through The Fall of Reach. 
 
Make me proud boy!
