I think most of you people are expecting way too much from Halo 4. The above shows that every mainline Halo game has scored lower than its predecessor although I expect Halo 4 to break that tradition and slightly outrank Halo: Reach. And even though I expect Halo 4 to be the best in the series I don't think it will score any more than 92.50%, I'm going to guess that it'll score between 90.00%-92.50% which is an amazing score range by anyone's standards.
I own all of the Halo games except for Halo 3: ODST and the only thing I can praise about them are their multiplayer components, I haven't enjoyed the single player campaign in any of the Halo games apart from Halo: Reach which was quite good but Halo 4 looks to be truly great in the single player campaign department as well as the multipayer component. I am genuinely excited about Halo 4 as everything I've seen or heard about it has impressed me which has never happened before with a Halo game. I think 343 Industries is doing a better job than Bungie ever did as much as the die-hard Halo fans will bitterly disagree.
