Portable Kickstarter or crowdfunded titles

2024 Update: A growing list of games and console-related projects here. 

2023 Update: A select set of notable campaigns for Switch, PlayStation or other formats that have caught my eye recently:

Mariachi Legends (Switch Physical option, funded, ongoing)

Ratatan (Switch, PS5, from the Patapon team)

Tavern Talk (Switch, Funded, Completed)

Rune Fencer Illyia (Coming to Switch, January 2024) 

August 2020 Update : Not expecting much in the way of new games or stretch goals, but still the odd project or delayed effort keeps coming. And the community lives on with more books and goodies. Keep supporting these games from brave developers still willing to support the Vita...

Prisma and the Masquerade Menace (Shiny Bolt) $80K Vita stretch goal (met basic)

Even though some games were funded, it seems the developer overestimated their skills or the power of the Vita. Games like Hand of Fate, BroForce and others drop the Vita version this happens, but don't be bitter at the developers, they try their hardest!

UPDATE: seriously, don't be rude to developers, the grief and abuse they get for trying to bring a project to fruition is staggering. I've read about families struck with cancer, developers being seriously ill and stressed beyond belief. They will try their best to bring a game home, but being abusive only makes things worse. If you invested in a project, that was your choice, let them do their job!
