Sorry can't say about the vault, but SM is a great game. I owned red one for 18 months sold to get Tspp. But after 18 months I got SM back in my collection and really like it. Particularly because its rules are so easy, and I can get 70-90% of the way to BR on almost every game but only make it there except like 5% so there is always some tense moments where I'm on the edge and need to complete one mode or another. It's got a good balance of easy and hard to the rules.
That aspect reminds me of Tron in that it's simple to do yet hard (for me) to get to SOS and I've yet to be to Portal (or SH on Spiderman).
The rules and call outs make the game great. I'm not sure vault since the call outs are different but the dmd display animations are way better on the vault. I kind of dig the old game because of the movie quotes and the major actors like Willem DeFoe and JK Simmons etc.. the vault voices seems like XM voice actors which I was ok with, but give me movie quotes like IM, Tron, and SM when done right.
I'd prefer the vault being new and better lit, but I happened to find a old SM that was in 99% shape so the only thing I really need to work on is the LEDs. It was done by the prior owner but cheap old LEDs so I need to work on getting them all replaced.
Color DMD is great too, the main reason I sold the old SM was because the DMD was so bad before the color DMD was released.
