An open PF like that isnt a bad thing so long as what is on there in the way of ramps, bumpers etc are well balanced. Scared Stiff is pretty open but a great game to play
Personally im glad to see a more open PF... others that have preceeded it are full of toys and its difficult to follow where the ball is due to bloody gimmicks.
With its theme and a more "retro" layed out PF.. it could well get a classic tag to it... but lets wait and see how well everything is placed..
...i am looking forward to playing this one though.. its taken my eye!
