Sorry if the title is a bit confusing, but what I'm trying to figure out is what home versions of arcade games were SIGNIFICANTLY changed for their console release. I'm not talking about levels that were left out or watered down graphics, I mean major gameplay changes.

Take UN Squadron for example, not only were the levels altered, but they added a whole plane and pilot selection section (which makes it better than the arcade version IMHO). Did any other arcade games get 'enhanced' like this? I'm mostly interested in SNES and Genesis games.
