I have both Namco Museum Remix and Megamix, because I am a freak. If DLC add-ons were a thing on the Wii, Megamix would've been one of those.
Lots of other arcade companies did the whole Breakout/Pinball hybrid combination for a while, it's just that Namco's sitll one of the only ones around to talk about it.
There was a pinball game on PS2 called Flipnic, and it had a mode that played a lot like Gee Bee/Bomb Bee/Cutie Q.
Seriously, look up Q Taro if you want to see what inspired Toru Iwatani to create games like Cute Q and Pac-Man.
