Custom Games! Will It be there?

One of the things I liked most about Halo 3 and Reach was it’s Custom Games, Forged or not.
Bungie added many more tools to work with in reach to keep us happy; but ,in Halo 4, you took that way from us with limitations.
Many great custom games forgers left Halo due to these drawbacks. I want to know that we’ll get that experience and even a functioning File Browser in Halo 5.
(There is a HUGE difference between arena forging and customs forging/Gametype settings)

List of custom games I love:

-Fat Kid
-Monster Trucks
-Janga Tower
-Basket ball
-Tank
-Griff Ball
-Monster Run
-Frogger
-Run indie Run
-Ghost Busters
-Teacher
-Cat’n Mouse

What I would love to work:

-Trouble in Terrorist Town(Juggernaut from reach but no fire)
-Prop Hunt(more like a mod but would becool)
-Team roulette(old game where you switch teams when killed or time based)

Just want custom matchmaking

All we need is a file browser. That’s it! Halo MCC has multiple forge and custom game platforms to work with. If you get a lobby with enough people you can switch between games with ease like playing halo 2 hide and seek and switching to halo 4 infection instantly. But no one has enough fun maps I’ve had to make or remake my fun maps to play with friends or add known forgers to get a racetrack or infection map for example. I enjoy forging but some people can make certain type of maps better than me. A file browser would solve it all.

On a side note as an alternative to file browser if they somehow added an import old maps option it could revive customs but that seems unlikely to happen.

I think Prop hunt would be pretty cool…
