Sadly, I bought ODST (overpriced DLC, anyone?); the silver lining is that I get into the Reach multiplayer beta. I'm definitely going to get the game, regardless of if it's good or not, simply because I devour Halo canon like no other. So far, though, it's looking good. I like the new accuracy system (for those who haven't seen, it basically makes each shot increase the size of the reticle for a short while), and all the new modes are looking pretty sweet. Plus, you know, needle rifles, assassination animations, and jetpacks.
I'm tentatively looking foreward to it. I think the stealth and squad-based aspects are probably overhyped, and it will end up being the same old Halo. But I will still enjoy the overall experience and whatever (very little) variety is added.
P.S. Has anyone seen the new Jackals? Badass.
