It surprises me that a lot of RvB fans aren’t Halo fans. Halo is what got me into RvB in the first place, and I can’t imagine watching RvB without knowing Halo canon.
I’m the other way around - I’d never had a chance to play Halo, nor any interest to, until I watched RvB and became fascinated with its universe. I’d been thinking about getting an Xbox for months, but that was what finally pushed me over, and I’m really glad it did. I’ve been making my way through the games and books and I’ve been enjoying them more than I ever expected I would. (I’d never even played a shooter before!) It’s interesting seeing it from the other side - now, when I watch RvB, I understand all of the references to it. Before, the only thing I knew was that Master Chief was green and that there were aliens, and now? Now I can actually appreciate it all.
Plus there is absolutely nothing like running through a multiplayer map and finding a “set” for RvB you didn’t expect. Coolest feeling ever.
