technical issues are frustrating, but expected. the only problem there is that they're compounded by the general inconvenience of the XBO OS.
the biggest problem with the beta for me is that it's mostly representative of what the final product is going to look like. i don't imagine any significant changes being made if they've made it this far in development. the final game will be polished and refined i'm sure, but things like Sprint, ADS and everything else holding this game back are here to stay. At this point, i'm accepting the fact that "Halo" means something vastly different to 343, and I'm not sure i want to support it.
