Very interesting poll!
Haven't decided yet, perhaps leaning towards DMD over SS, just - but there are so many good SS titles out there...
I just haven't ever put the time into EMs so I can't comment on them.
Funny thing was at the PSP pre-Christmas meet there was an Embryon (wide body Bally SS machine) available to play. It was a slow old thing, but the challenge of playing it was still a lot of fun. Most pinball machines are fun if you give them a chance, they are pinball after all. Some I wouldn't want to own, but I certainly don't mind playing them.
