Yeah, I'm fine with jumping around worlds from games and shows and all, but don't call it a multiverse game if it takes place inside the internet.
Remember that Fairly Odd Parents movie, Channel Chasers? They didn't call it a "digital multiverse" when they ran around inside cartoons. They just called it an adventure inside the TV. Besides which, the concept of multiple multiverses is just silly, because the multiverse concept itself covers every possible reality.
