I guess I’ve never paid attention to the push for interactive tv other than VOD... however it’s a fairly good experience IMO.
During live games it is (partially) hosted by an actual person who is paying attention, reacts and uses the names of those who do well… while I’ve not had a chance to play in a while, during the beta there was a significant amount of back and forth where on a few occasions they’d ring a previous One and talk to them for a min or two (on the air), as well as read shout-outs that were sent to them.
It is a very different experience though than the traditional gaming experience we’ve come to know thus far playing something like Halo 3 (aside from the lack of 12 year olds screaming in your ears)... rather than just be you vs everyone else, or those in the house (mostly) playing against each other but with the inclusion of a few other people online for background targets... you do feel a lot more involved with OvO than you do other games IMO, you really feel like you are part of it rather than just watching a game show... and this being said by a guy who hasn’t watched a game show (other than Junkyard Wars (if you can call it that)) in over a decade.
