I would greatly appreciate a feature where you can have the option to host a Custom game session or join a public one that has already been created.
It might be a little more difficult than I think but if Halo Custom Edition on my PC and a few indie knock-offs can make it work I’m sure 343 can pull it off.
Just show the person hosting the game, the name of the gametype, name of the map, and the ping status, and let us pick whatever is going on.
I’ve loved playing customs since H2 but trying to find randoms who invite or even play customs anymore is like pulling teeth.
The closest I think most people can get is Action Sack.
