This is what should the FUNimation crew do
They should make tokyo ghoul into a video game like a ps3 and xbox and next gen consoles. IT WOULD BE REALLY COOL. IM JUST A BIG FAN OF TOKYO GHOUL. IM JUST GIVING MY OPINION THATS ALL.
I am afraid funimation doesn't make video games so that isnt going to happen.
The only chance of getting a Tokyo Ghoul video game is if a Japanese developer makes one and someone publishes it here in the west. Unfortunately the chances of that happening are basically 0%. So don't get your hopes up. However its always nice to dream!
