Rating is not the issue with Metroid. The "problem" is a lack of online mp. Im not saying turn Metroid into Halo or whatever FPS, but maybe take a page out of splatoon and make it more fleshed out. So Nintendo has a rated "E" TPS in Splatoon, why not add a T or M rated FPS (whether new ip or Metroid )?
With Nintendo now charging for online, they have to bring the online games to justify the subscription.
