Jet Set Radio Wii entered production but never got past concept art.
Project HAMMER Wii original vision.
Castlevania Ressurection Dreamcast
Streets of Rage 4 Dreamcast
Dragon's Crown Dreamcast. Yes the game came out 14 years later but the original art was very different and would have been interesting to see the original vision of the game.
Legend of the Blade Master RPG Dreamcast
RavenbadeRPG from Retro on gamecube. Development was a mess but I would love Retro to revisit the idea.
I kinda wish we got the Project Dream RPG on SNES instead of Banjo on N64.
Sadness for Wii.
