Microsofts flagship title didn't get much air time. I dont think they showed enough or at least enough to get me to spend 60.

Thoughts?

I don't think anything in the conference got a lot of time.

What they did show was also underwhelming

Thoughts on what? They showed it for about 10-15 minutes. Perfect amount. Showed of campaign and MP. The game informer details were not said so I thought that was odd.

I was waiting for a game-changing new gameplay feature during the e3 presentation but I didn't see any. Like Fallout 4 integrated the house-building, scavenging to construct stuff, over 700 weapon customizations that affect even the look of the weapon, the Dog interactivity, new dialog tree and voice over for protagonist, improved character movement and feel, etc.

I guess Halo fans will be happy playing more from the franchise they love though so it will be ok for them. I too like to play more of the same from franchises I love, so I won't stand here and criticize them for that.

I felt indies got too much, Halo got less than what I thought it would. 

They already know that you're going to spend $60.

It is halo. Nothing more nothing less. You know what you get with halo.

They spend like 10 minutes on it.
That's more than enough for a conference with a limited amount of time.

Maybe because the conference was shorter than prior years?
