What's up with this revisionist history people like to do?
Dance Central Spotlight is irrelevant because Kinect is dead? Mkay....it wasn't at the time and the game came it to decent reviews
Project Spark - "Conner DLC never came out"...that's just not true. Game "lasted" about 3 years...not too bad, but definitely a missed opportunity
Sunset - all you can do is call it a commercial flop? What the hell does that have to do with it making their conference bad? The game was damn fun and unique and the only thing you can contribute is that it didn't sell well, as if that impacts its existence as a product to play today.
Halo MCC - Has had a fuck ton of issues but many have enjoyed it for the SP at least.
RotTR - First of all, it wasn't even announced as timed exclusive until Gamescom. A short trailer was shown at E3...
Half the things you said don't actually contribute to the show itself being poor.
