I truly think that halo would benefit a lot in money wise and other aspects if they would just consider putting the game on different systems. So, I bought a ps3. It's a good system. I don't know why halo can't be on it. Is Microsoft really that greedy that they can't put one of their own games on different systems so they could make more people happy and get more money. So, tell me what your opinion is. CHAT IT UP WE NEED AS MUCH ATTENTION AS WE CAN GET!!!
