Everyone is entitled to their opinion. For me however, the campaigns personally mean different things on how I felt during that time, who I played with. I rank the campaigns Halo:CE> Halo: Reach> Halo 3> Halo 2> Halo 4> Halo:ODST Now you may not agree, but it's just the way I felt as I played them. Real life affects how we play as well, as well as our mood. I don't rank campaigns solely on which had better graphics, better sound, et. But how they played, how I felt, what they meant to me, how they were designed. I know a lot of people hated Reach, but I loved the campaign. I hadn't felt that way since Halo: CE
