UberSpartan, you ought have read the posts after those that you quoted. That was cleared up almost immediately. However, Halo Wars is not set before the first book. Though there were Spartan 1.0s before the first book, they did not wear armor, even in the Spartan-IIs didn't have armor for a while, and thus, it must be the Spartan-IIs in the trailer. Also, the Covenant War didn't start until the first book, so if Halo Wars was before that, then what are the Covenant doing in it? The answer, it is during the first book.
owner, what are you trying to say? Your spelling is illegible. I picked out RTS (G...whatever, RTS is how it is commonly refered to), and I picked out something about not haveing anything to do with Halo. What the heck do you mean by that? Do you mean the trailer has nothing to do with Halo? Do you mean the game can't have anything to do with Halo? Anyway, I agree with Jak, Halo is a story and can be properly applied to any genre (though I hope they stay away from the MMO genre).
UberSpartan, I don't know if Halo CE was originally going to be an RTS, but I do believe it was originally presented as a TPS (third person shooter). Perhaps it was an RTS before that...
I like pi.
