I dunno. I don't understand how the shaker integrates with the theme. I don't really get why a shaker needs to be in every game. Earthshaker? makes sense. Sparky? Well ok it's got a hammer and an electric chair so I guess you can make a case those things shake. But otherwise to me the shaker can be gimmicky. Tron? no need for one. I prefer games without them honestly (despite owning an earthshaker) because it makes it a bit weird to nudge a shaking game.
