So, who can play 'em all?
I start most days with BubbleHEAD's (Dan Roth) JackBot, which I believe to be VP6 (released in 2002) but also plays fine in VP8. It's nice and slow, so if I can't at least hit the 9.5B replay in the first game, I go back to sleep. Kinda like seeing my shadow...
Thanks to DnaDisturber's PINemHi Leaderboard, I took an interest in VP9 tables as I encountered them in the PINemHi Challenges, but got a late start because my lame computer couldn't handle complex graphics, alpha transparency, and later, primitives (whatever they are)...until VP was ported to DX9. Suddenly my rig played VP9 BETTER than it could play VP8 (!)
Anyway, due to vendor apathy regarding table serviceability, I played almost no pinball after about 1985, but I do remember playing JackBot a few times when it was new in late '95. Fast forward to early 2010, and VP has had most of my attention since.
So, I currently have a small group of recent favorites with Attack from Mars, Medieval Madness, Scared Stiff, White Water, and the Klingon to my Kirk; Black Knight 2000. I don't know how many models there are, but I have yet to get 15M on any of them...Grrrr
Two others I liked were Star Trek the Next Generation (too much time spent trying to time the cannons, though) and The Lord of the Rings, which had a couple of spots on the playfield where a ball entering one of them would slow the entire game down to 3 or 4 FPS. Once the ball traversed said spot/s, the game resumed normal framerate---but multiball was hell, so I gave up.
I could go on for days...plus, there is VP-TEN now, and I may have W8.1 soon, followed by a Haswell or Skylake CPU and appropriate motherboard, and a 1050Ti to round it out. Until then.....
