Uhh, is the game going to have a large enough population to sustain this?
What a bad opinion to have.
If I wanted to play Custom Games, Halo 5 is right there, otherwise why would I bother with Halo 3: the game with really awful aiming controls, map design and weapon balancing when Halo 2 AND Eldewrito are easily accessible.
Vanilla H3 is a fuckin wash
