Even I remember well, Slam Tilt is a MS-DOS game..
anyway, Pinball Dreams 2 is NOT from Digital Illusions, it's from Spidersoft, although it was published by 21st century entertainment (actually, Slam Tilt also was published by them)
Spidersoft made a few odd pinball games, and I think they are rubbish. The graphics are nice, but the tables layout are crap. I recomender to leave them alone
