Poor Mega Man can't catch a break - he didn't get a spot in the latest Marvel vs. Capcom game, Capcom won't do anything with the license, and the latest big Mega Man game was a crossover with Street Fighter that a fan made by himself. But one that really stings is the cancellation of Mega Man Universe - which would have been a 2.5D (fancy term for "no one buys 2D games but we don't want to put the effort in to make it fully 3D") semi-recreation of Mega Man 2, except with a level editor and the ability to totally customize Mega Man with different appearances, weapons, and abilities.
Why did Capcom put the kibosh on the Blue Bomber? Well, the very specific and not-at-all vague answer was "various circumstances." Good to know.
Sadness sounds like what would have been one of the most terrifying games ever, for a number of reasons:
The game would have seen you in pre-World War I Ukraine, as a mother protecting her blind son from monsters and madness. It was being designed for the Wii when everything fell apart - due to being stuck so deeply in development hell that the team behind it was never able to produce screenshots, video, or any kind of demo. The dream of the scariest game for the Wii was dead.
Although if you really want to see something truly scary on the Wii, try the Mario Party 8 mini-game "Flip the Chimp" sometime.
There was a time where Rare was known for quality, innovative games, instead of animated .gifs of their spinning logo popping up on Tumblr. Back in the early 90's (pre-Donkey Kong Country), Rare was going to make their SNES debut with a game called Wrestlerage - which would take the best aspects of wrestling games (cool moves, ridiculous characters, total commitment to realism) and transpose them into a Double Dragon-esque fighting/adventure game. Essentially - a way cooler Double Dragon game, where you could perform choke holds, dropkicks, and pins on the random street thugs you ran into.
However, Rare was unable to get a major wrestling license, so they had to make up their own wrestlers. This left investors nervous, since it would be tough to market a game without any name recognition, and the game was canceled. Personally, I think their marketing strategy could have just been "IT'S DOUBLE DRAGON WITH COOL WRESTLING MOVES" and it probably would have sold out immediately.
A lot of TV shows and movies used to include hilariously over-the-top videogames, depicting insane amounts of gore and violence, as a way to comment on controversial games like Mortal Kombat. But if you actually played Mortal Kombat, it was never really quite as bad as the media liked to say it was. But...what if it WAS as bad and ridiculous as those fictional games (such as The Simpsons' Bonestorm)? What would that look like? And - wouldn't it be pretty awesome?
Answering all these questions: Thrill Kill. It included limb dismemberment, in-awful-taste sexual references, and a hilarious amount of violence. The four player fighting game would have done away with a life meter - instead replacing it with a "kill meter", that rose as you brutally murdered your opponents, until your bloodlust was so high that you became superpowered and performed "Thrill Kills" - horrifically-violent finishing moves that were in no way stolen from Fatalities.
The game was so rife with violence, that publisher EA refused to publish the game - even though it was nearly 100% complete, on the grounds of it being so stupidly violent that it would forever damage their image. If only they were aware that in 2013, literally nothing could make anyone think less of EA, maybe they would have realized they coulda at least gotten a little bit of their money back.
