Well, yes, people did play those. Nintendo advertised these back in the days when Pokemon was hugely popular so the pinball game sold more copies than if it was just pinball, without the Pokemon veneer, and Pokemon Puzzle League/Challenge was the successor to Tetris Attack. There is nothing stopping Game Freak from re-releasing these games now and with the capabilities of 3DS WiFi, puzzle gamers and pinball wizards can have their shot at fame in the GL standings, just like battlers.
I gotta like the shiny form, myself. I liked Shinies so much I spent the money to get a Gameshark (remember those) just to spam as many Shinies as I could.
