Am I the only one who is thinking 'Mario invented the Platformer as we know it today'...?
In any event, I think there's plenty of games that got overshadowed not so much by 'Mario', but by the same thing that has plagued games since their creation. A lack of marketing or because they were made by smaller companies. You could try to blame the fact that some of these games didn't take off on Mario...or the fact that they just didn't take off themselves.
Also, some of these games did take off, but only in certain regions. Like Bonk and Doki Doki Panic, which spawned entire series of games in Japan and are still going.
In any event, there's probably a few I could name. Bugs Bunny Birthday Blowout (NES), Duck Tales series (NES), Dragon Ball Advance Adventure (GBA)....but the thing is, I don't think 'Mario' had anything to do with why they didn't get popular. Heck, some of these games did get popular back in the day when they came out, as well as the games that have been suggested in the thread already. There's just a difference between 'popular' and 'sustained sales and good gameplay'. And Mario has a core development team which has been making and innovating a solid product for....25 years. I can't think of any other platformer series that can make that claim.
