There was an updated version of Space Cadet on the https://en.wikipedia.org/wiki/Marble_Drop I got as a kid. (I somehow played that before I found the standard windows version, so I might be a bit biased. ;) ) The Marble Drop version is way more polished windows version, everything 'just works' a little better. Shots line up better, graphics are better... it feels like a really solid patch. Plus, two new tables, "pirates" and "dragons"!
