I rate "Pro Pinball: Timeshock" as the best PC pinball table ever. I'd LOVE to see that one here on GOG.
(I'm also kinda fond of the Worms table in Team 17's "Addiction Pinball" :)
This one is definitely okay, but unlikely to match up to those tables.
Music is a bit rubbish, to be honest, and there was one amazingly irritating sound effect I had to disable (I recommend replacing Data\Sounds\gumikopp.wav with a copy of something unobtrusive like kar1v.wav), which was a bit of a downer as far as first impressions went. In general, audio is competent, but a bit mundane.
Visually, it's quite pretty. I do wish I could get rid of the 'player' reflection on the ball, and I wish there was a view that DOES NOT MOVE. A seriously weird omission, that! (I know they went to the trouble of making it in 3D, but that doesn't mean you HAVE to move the camera.) That said, the F2 view is pretty much fine.
I've only played each table for a few minutes, so I certainly can't say anything definitive about gameplay (and I'm not good enough at pinball to comment much in any case), but it seems to play smoothly and handle well.
Options are a bit lacking (the Pro Pinball tables are almost overwhelming in this regard), and I wish it could run in a window, or handle ALT-TAB.
All in all, seems like a decent pinball game, and ought to be good value at the price. (Good to see it at $5.99.)
