Set for the PlayStation 2, Capcom Fighting All-Stars was a promising looking 3D fighter that was bringing together plenty of Capcom's biggest characters together. Characters from Street Fighter, Final Fight, the under-appreciated Rival Schools and Strider were all set to appear. A 2D fighting game, Capcom Fighting Evolution, would later bring this idea to life.
Final Fantasy Agito is the mobile tie-in to Final Fantasy Type-0. While it was released on iOS and Android, it was also slated to release on PlayStation Vita. Sadly, the port was scrapped in 2015, and the localization was also cancelled.
There was a lot of hype behind Human Element. The Robert Bowling directed first-person shooter was set to take place after the apocalypse and would place players on 5v5 teams. Ultimately, developer Robotoki was unable to find funding and the game was cancelled in early 2015.
The sixth entry in the Legacy of Kain series was set to come to PlayStation 3, but was cancelled in 2012 after Climax Studios spent 3 years working on the title. Called Legacy of Kain: Dead Sun, the action-adventure title's multiplayer mode was turned into the free-to-play game Nosgoth. It was going to be the first entry in the series since 2003's Legacy of Kain: Defiance, and was set in the future.
Now that everyone knows how awesome Mario Maker is, imagine playing the same concept with Mega Man levels. PlayStation 3 title Mega Man Universe was supposed to be that, and was going to allow players to create their own levels. Players could even customize the characters in the game and change how high Mega Man could jump, and what weapons he could use. Sadly in 2011, Capcom announced that the game was cancelled. Hopefully the idea will get resurrected, as it seems far more promising than Mighty No. 9.
Prey 2 has the distincton of getting cancelled not once but twice. That's an impressive feat. It was originally announced in 2011 and was being worked on by Human Head Studios. Development then shifted to Arkane Studios in 2013. That didn't last long, as a year later Bethesda Softworks finally announced that the game had been cancelled. It's a shame as Prey was one of the best games of 2006, and there was a lot of potential to build on.
If you thought that a Silent Hill game directed by Hideo Kojima was too good to be true then you'd be right. It was supposed to happen, though, as Silent Hills was announced by Konami via its "playable teaser" P.T.. To add salt in the wound, director Guillermo del Toro and actor Norman Reedus were also involved in the project. While we will never see Silent Hills come to fruition, hopefully Kojima will be able to create the horror game he wants to do now that he's separated from Konami.
Star Wars 1313 was supposed to finally give Star Wars fan the game they deserve. It wasn't a movie tie-in, nor a LEGO platformer. It was a AAA action game that looked an awful lot like Uncharted. Sadly the game's days were numbered as The Walt Disney Company ended development on the title after they purchased LucasArts in 2013.
While it probably wasn't going to be a great game, it's hard not to be curious about how This Is Vegas was going to turn out. After all, Midway spent over 40 million dollars (!!!) on the Surreal Software developed game. It was set to recreate the Las Vegas experience on consoles, and was one of the many reasons why Midway had to close their doors in 2009.
Idol Minds was working with Sony San Diego on Warrior's Lair, an action role-playing game for PlayStation 3 and Vita. It was revealed at E3 2011, but then news stopped coming out abut the title. It would undergo a name change before Sony once again went radio silent, and in 2013 it was finally cancelled. It could've been one of the Vita's key titles, but instead is a footnote in gaming history.
