My opinion I think the team that does yakuza could make a great Shemnue game with Yu Suzuki as the director. Especially on the new Yakuza game engine

It was a very excellent movie. The pacing was just perfect. Suspense was perfect.

For one his voice needs to be changed. The perfect actor to voice sonic is Jaleel White. The actor who played urkel.

My suggestion would be to track down the old team and get some help from segas developers specifically the one behind yakuza that would work well.
