Quoted from davewtf:
sinking institute is kick-azz
I agree...the sinking institute combined with ES shaking ability blew me away the first time I experienced it! If ES is on a non-carpeted floor you can feel the vibrations through your legs. I think the shaker motor is the most recent / older unique feature used on newer machines today! I also love the originality of the DW time expander being able to reverse depending on game play and of course FH Rudy.
