I don't mean to go on but while I'm here...my thoughts on Halo 4 tournies.
Overall I would watch again, thoroughly enjoyed it and I'll certainly tune in next time. I'm really getting into the LAN to pro tournament progression right in front of us. AGL is really coming a long way but some polish is needed all around.
The stream quality, audio quality, commentating and Astro listen in are all very solid where I just think they need some live blogging or real time statistics as part of the feed, always on basically. Spectators also need somewhere to go to see all the scores, settings, playlist for a match up etc. The AGL website would do well to support this in real time and with multiple browser tabs, devices or monitors this could easily double their viewing within the same audience.
Producing that sort of content depth and polishing up the live stream online editing, graphics, segues and perhaps bringing some quick interviews pre/post game to the streams would all be positives. I give them plenty of kudos and see them making leaps and bounds with each event, great work and thanks to the sponsors too.
Perhaps they could do some quick post game chat/Q&A with the coaches/players too, maybe bring in a losing bracket coach/player for some inside comments during a finals game etc?
Other TV-style features I'd recommend are instant replay for the live stream or a post game highlights reel/video post game/series would do well too. You could even provide some of these tight interviews or replays during the parts in between games or matches setting up. You could also do team Q&A on the AGL website prior/post the events. Further you could even have teams available at certain times to answer questions in a live chat or forums post/reply. Fans love interacting with the pros, web has many advantages over traditional TV based sports, use them.
I'd also like to see more complexity in the streams, use Twitch or AGL website to provide an interactive stream system e.g. 4 players from the same team in a quad feed box and you can simply click to then view one stream full screen at a time. You could also provide the "event directors" feed so they do the editing. You could also provide a dual compare, one stream from read and one stream from blue. After all we have a guerrilla style stream system that is interactive and web based, this should be exploited for its feature advantages.
These are just some ideas anyhow, more spectator features than just the commentators or gameplay alone. You have this big event and should extract as much content from it as possible. Rather than a one weekend show you could literally turn it into weeks worth of content such as Q&A web articles, photo galleries, Video On Demand etc. After all it's all about butts in seats and if you can get the existing audience to view twitch and the AGL website in the same browser session you've doubled your advertising streams and views, sponsors like that sort of thing and fans love the added features. When you expand with content over say two weeks, one prior the event and one after the event, as I describe you also create a sustain marketing and content schedule that both fans and sponsors both enjoy the benefits of.
