I love Halo and Bungie. The only games you'll see me play thats NOT halo are Battlefield BC2 Battlefield 1943, Flight Sims, Oblivion, Skyrim, and Minecraft and CoD on occasion.
Don't know if you're talking about "3" or "Reach", but I've played Jenga Wall on Standoff in "3", and thinking about making a variant in "Reach".
