Wow, this is surprising. Gamers with long memories will recall a never-released Wii exclusive game called Sadness, developed by now-defunct Polish studio Nibris. The game had some cool promises, including a horror plot set before WW1 and a color palette completely in black and white. That said, the game always seemed like a pipe dream to me and has been dead for years now.
According to an exclusive interview at Nintendolife, indie studios HullBreach and Cthulhi Games--both with their own individual projects planned--are teaming up to revive Sadness on Wii U for a projected 2016 release. Both studios have past experience and were connected to Nibris at some point, so I'm cautiously optimistic about what they could do for this game that never was. Supposedly they're starting from scratch with Unity engine (the original was on Gamebryo) while trying to stay as faithful as possible to Nibris's original vision.
This is one of the reasons I love the indie scene and direct download. While Nibris's aspirations always seemed foolishly optimistic at best, indie-friendly development tools and a market that cuts out the middleman have made small, ambitious projects the rule these days instead of the exception. It's also great to potentially get a Wii U-exclusive horror game. I'll be keeping a close eye on Sadness, as well as both studios' other games, Ex Oblivione and HullBreach Uncloaked.
