Wcs is way too easy..got board with mine almost immediately like every other J pop game. The only J pop game that has stood the test of time in my collection is Totan because my wife would kill me if I sold her precious.
BSD was my first machine sold it to finance a new game and then promptly bought another BSD within a year. Have owned mine for 20 years. It makes you a better player by forcing you to trap the ball and make the shots or pay the concenquences. Fantastic game if you want to get better at Pinball this and f14 are good sparring partners.
IM is an excellent game great theme and also kicks your ass. I’ve been loooking for a reasonably priced one for some time when one pops up near me I’ll buy one.
I would buy either BSD or IM. The good news if you don’t like them off loading them will not be an issue. Good luck with your next acquisition.
