It may also dictate what the developers/producers/directors think the audience prefer the game.
"Lots of people choose violence, therefore this should be a violent game.
Thar's kinda sad. I don't mind mild violence but kinda hate if it's done like how Mortal Kombat series did.
It's like Pac-man invaded this cyberspace and is somewhat of a foreign unknown monster to it... which makes sense given this place is for Sega CASTs.
Or may be SEGA has destroyed other company's cyberspace and some of the runaways came to SEGA cyberspace.
My guess, early attempts at bringing the CASTs from cyberspace to reality via advance holograms.
May be, that would explain why the game's suddenly came to real world in humanoid form.
