Im just going to add my two cents to this long list of opinions. Ive talked to a few Halo fans which are also online players and the consensus is that Halo CE, Halo2 and Halo3 were GREAT!!!! The graphics got better, more maps and the storyline continued. However Halo Reach dramatically changed the Halo gameplay. In my opinion the makers tried to make it like COD with all the new medals, the abilitities(jet pack, personal shield, run ability, etc etc). Thats not Halo. To me Halo3 was the pinnacle. It took what was great about Halo CE and Halo 2 and fine tuned it. The online multiplayer feature in Halo Reach was changed too dramatically. If I want kill streaks, weapon attachments, extra abilities etc etc etc then I will play COD. Halo needs to remain Halo. Its not COD and we dont want it to be. I love the story line. So far its been great but dont change the game around. Also bring back the skill level. When playing online I want to play similar skilled players. Just because someone plays a lot doesnt mean they are good. The new ranking system does not incourage you to play ranked games. It encourages you to play Fire Fight in order to accumulate more points so you can rank up. The previous ranking system from 1-50 was just right. Lets bring it back.
Just my humble opinion
