Excellent... just ordered the Codex BRAND NEW on ebay for like 12$ total (Included shipping). I HIGHLY recommend anyone looking to pick this game up to goto ebay cause you can get the total codex for $12 BRAND NEW there.
I think Myth is interesting in the sense of (I'm 29) I totally see Myth's, "Roots" in the Halo universe / physics. It was quite common to see a dwarf head go flying 1000 ft in the sky after a (Forget the name of the lighting wizards) lighting bolt blew him to pieces lol. Well you see it especially when driving the warthog.
Not to mention the terrain, etc.
Watching Bungies' video they talk about Halo was originally going to be designed as a RTS w/ Halo - like shell. Wow...
Which is kind of upsetting in the sense of seeing Bungie had already mastered the art of RTS and was originally going to make Halo a RTS why they didn't take the lead on Halo Wars and make it better than average. (Granted... I haven't played Halo Wars near enough to judge it fully... but it certainly didn't suck me in like Myth did)
