I had ST as well & really enjoyed it. After having ST in my lineup for quite some time, I replaced ST w/ SW's & I'm glad I did. SW's has an excellent theme presentation w/ a lightning fast SR flow. The code is excellent, as every game played is never the same depending on what path you take. SW's Premium is the way to go, simply for the hyper-loop & exploding death star. SW's will compliment MET as MET is a "bash" strategy & SW's is a flow-fest rush. I also could care less about the SW"s theme, but this title is incredible pinball!

I have had some play on IM, but cannot give insightful details. IM is definitely fun, as the upper loop layout is unique & challenging. The LCD presentation is well done, but if the music is not your thing, that could be grating.

No doubt MMr is a timeless classic that has great flow & excellent theme integration. MM has absolutely the best toy in pinball, but is lacking w/ code depth. After achieving the wizard mode five+ times, unfortunately this title could grow stale.

SW's would definitely give a nice variety w/ your lineup of Tron & MET. Each title is different in layout & contrasting w/ theme. Tron, Met & SW's for variation & to compliment an incredible lineup. I wish you well in your pursuit of YOUR perfect machine!
