Project Giant Robot Wii U. Maybe Labo Robot is the reworking but we don't know.
Anyone remember the canceled Elder Scrolls game for PSP?
Earthbound 64.
Final Fantasy VII N64
Halo DS
Cosmic Walker Wii (we got 6 seconds of footage and then nothing ever again)
One that hurts is Cry-On for Xbox 360. From Mistwalker (Lost Odyssey and Blue Dragon)
Then we have The Grinder an FPS from High Voltage. We never got official word it was canceled but yeah.
