Well, there are stray mentions to Halo (the "Great War" is the Covenant-Human one, Master Chief is mentioned in the first episode, the Sarcophagus held an Engineer), and the RvB events occur far away from where the games occur. The universe being shared is not that difficult - Project Freelancer could even be a simultaneous thing to the SPARTAN program.
