Well seeing as BoN is expanding to other games like CSS, why not into Halo? All you need is a few good maps for a rotation. If you go regular Halo, I'd suggest; Blood Gulch, Death Island, and Sidewinder. If you go Custom Edition, I'd suggest Coldsnap, Extinction, and possibly one of the RPG maps. Of course this is just a suggestion, but I've seen a lack of some dedicated servers with good maps lately.
