I only cared about Halo's lore that was CE - H3....maybe Reach I think Chief floating in space was the perfect ending, he came out of the cryotube in CE, went back into it one last time in H3, it was the most emotional, and inspirational ending in any video game I could think of. I still love the series (if they ever get it out of the mud) but I play for the wows of the engine and the gameplay, the multiplayer also
