You pretty much got them all dude.

My personal picks for biggest flops has to be the capcom drama, the youtube license, and the aliens colonial marines fail. 

You got them all. The FEZ 2 one is that weird mixture of satisfaction (a jerk getting his just deserts) and sadness (his fans and the artists who were working on the game get screwed over).

Also, fuck Colonial Marines.

For me, it was the Xbox One. From start to finish, Microsoft gave birth to a console quite literally from hell. A requirement to be always connected to Xbox Live, DRM, a spycam used by the watchful eyes of the NSA, the inability to trade or sell games, and as quoted by yourself, an over-emphasis on everything but the games themselves. The staff also proved themselves to be both incompetent and stupid by making the situation worse and worse, an example being agents at Nintendo's E3 conference trying to detour audience members to buy the Xbone.

Clearly, they had little choice other than to do a 180 on their original plans for the Xbone, otherwise the backlash would get twice as bad, and most of their already shrinking fanbase would defect to Microsoft's rivals, a good example being Sony. The only questions that remain are "What were they thinking?!" and also "Will Microsoft do another 180?" In my case, I wish not to find out. I'll be sticking with Sony from now on, at least THEY care for their consumers.
