I know the feeling. Had an ACDC Pro for a year now, and have picked up 6 other pins since that time. It's not often I can peel myself away from ACDC to play the others, I kind of have to force myself to play the others. For ACDC I'm always playing for score, and it's just so addicting trying to build big jackpots to cash in. Some of my other games look better, have way deeper rules, more modes, etc., but it's always almost all ACDC all the time. It also feels like you have to have 100% focus when playing because if you miss a shot it often ends badly.

I would note that the ACDC pro version is quite a bit faster than the premium version. The premium version almost feels slow when I play it. ST feels similar in speed to ACDC pro to me, perhaps just a smidgen slower due to not having TNT and Thunderstruck standups only halfway up the playfield. So yeah I'd say ST is faster than ACDC premium. This also makes me find ACDC pro a very dangerous game as missed shots careen off of everything until they often end up in the drainy outlanes - I've come to actually kind of enjoy this as it's like living on the edge. Nothing boring about this game. As much as I love something like ST, I'm actually starting to get a tiny bit bored of it - I think it's just a bit too linear in not being able to build huge jackpots to cash in.
