There are very few game types, this has already been addressed by lots of people (though 343 has still yet to confirm they’re actually gonna make all the basic Halo game modes actually exist, like assault, KOTH, Infection, etc.
Even more than that, though, the customizability of existing games is severely lacking. You can’t just set things in the game settings, like multi-flag, neutral flag, one-flag, etc. You also can’t set equipment or set a weapon slot to random. The settings are incredibly lacking. Not to mention, the radar scalar (among other settings) don’t even work right. The percentages as compared to the actual values you get in the game are all wrong.
I reported that in a ticket to @343 months ago now, and not a single thing has been done to address it, despite that it’s a very simple calculation error. Should be an easy fix for a “professional” programmer, and yet nothing.
It really feels like they’re not even trying, and if it keeps up this game is gonna lose even more players because of it.
