Im interested in playing custom games like castle wars and sumo but i dont have many friends and would like to know of popular hosts’ gamertags of such games.
It’s easy enough to get a custom game going. Just download the maps, play a game in Arena, and invite everyone from that game.
It would be awesome if they had a “Spartan Forged” option with a featured selection of maps added to the rotation each week. Perhaps have a forum on Waypoint to decide on next weeks featured maps
If you get a custom lobby going let me know 
Thanks everyone
Best of luck, custom games may be hard to set up, but when they get going, they can be a blast.
