First off, I don't know absoulutely everything about Halo, but I have read all the books at LEAST 6 times each (I have no life i know). But I just want to add my 2 cents =P
Second, I'm glad someone was at least able to point out the truths about the assault riffle and battle riffle.
To be more specific, the assault riffle from Halo 1 (the MA5B) was STANDARD issue for everyone, not just the PoA's crew. Then in First Strike, a few Spartans find some experimental equipment that has not fully been tested yet, meaning the pistol from H2 and the battle riffle. That is the first appearances of those weapons.
As someone already said, the Spartans started out from a group of around 170, but they only had funding to train half that (70-75 somewhere around there). Then during training, they were all altered with some physical modifications. Making them faster, denser bones, etc. But about half of the 70 Spartans were killed because their bodies rejected the changes, and then twelve of them had side-effects that kept them from active duty with the rest of the Spartans. So that left them with around 35 Spartans. When Reach fell to the Covenant, the mojority of the Spartans were sent groundside to defend the generators of the orbital guns, leaving just John alive. But when we go to First Strike, several Spartans survived, but by the end of the book there are only 5 left. With one of those being kidnapped by Dr. Halsey (the genious behind the Spartan project).
As for the armor, I'm not quite sure what the version without sheilds looked like. But in my opinon, I think that the amor for Halo Wars looks too advanced for being the first contact with the Covenant. I do agree that it should be bulkier, as that is how it is described in the books. And I do understand that the Xbox 360 is a better system, so why not take advantage of that? Except that it contridicts the story line as said before.
I like the look that they gave the Elites, they shouldn't have any real size restrictions. They should be just like humans, we come in all different shapes and sizes, why can't they?
I own Battle for Middle Earth 2 for my 360, and I'm not too awful impressed with the controls. However, they are the best I've ever seen for a console thus far. So having a history in RTS's, I'm hoping that Ensemble Studios can do an even better job with the controls for Halo Wars.
But of course, there will always be some contradictions. There are quite a few between the exisiting games and the books. Such as the PoA is suppose to be a fairly rare class of cruiser since its class had been decomissioned. But in Halo 2 there are quite a few of them around Earth, which could be due to the fact that the UNSC was running low on ships, so they recomissioned all the Halcyon class cruisers they could find. So we will just have to live with the contradictions.
And thats my 2 cents.
