GT5 to GT6 is one that comes to mind. Also wasn't Wii Sports Resort the true sequel to Wii Sports? In that case the drop isn't that bad.

I had some a page or so back.

Saw the list from Previous page. sad truth on those good games. God of war, xenosaga, etc. And of couse all wii to wii u games.

Maybe it`s time for some of these games to move to smartphones? A Brain Age game on the go on smartphones might not be a bad idea...

When you compare to consoles with radically different user bases, drops in sales are not that surprising.

Yeah, Angry Birds is a BIG drop.

Original Angry Birds (2009):

Angry Birds (Android): ~221 million global downloads (free)

Angry Birds (iPhone): ~28 million global downloads (price = $0.99)

Angry Birds HD (iPad): ~5.1 million global downloads (price = $2.99)

=

~334 million total global downloads

Compare this to the latest sequel:

Angry Birds Stella (2014)

Angry Birds Stella (Android): ~12 million global downloads (free)

Angry Birds Stella (iPhone): ~1.4 million global downloads (free)

Angry Birds Stella (iPad): ~693K global downloads (free)

=

~14 million total global downloads

That's a drop of ~320 million Angry Birds downloads.

what about tetris to tetris 2?

Here is Candy Crush Saga:

Candy Crush Saga (Android) (free) = ~222 million global downloads

Candy Crush Saga (iPhone) (free) = ~99 million global downloads

Candy Crush Saga (iPad) (free) = ~25 million global downloads

=

~346 million total global downloads

*w/ Facebook data, the number is over 500 million (at least 1 out of every 23 Facebook users is a fan of this game)

Compared to Candy Crush Soda Saga:

Candy Crush Soda Saga (Android) (free) = ~79 million global downloads

Candy Crush Soda Saga (iPhone) (free) = ~13 million global downloads

Candy Crush Soda Saga (iPad) (free) = ~4.0 million global downloads

=

~96 million total global downloads

~250 million total global download drop

The drop isn't nearly as bad with Candy Crush Saga as it is with Angry Birds.

Rovio Entertainment has over-saturated the franchise...as a result, the Angry Birds franchise is quickly losing relevance with the average casual consumer.

Not to mention that Candy Crush Soda Saga still has room to grow, while Angry Birds Stella has been flatlining.

There's probably a reason companies like Zynga have been having huge problems. If you make a living off of creating fads; you'd better make sure that you grab a new branch before you let go of the old one.

I'll not include Wii Sports in my list because it's not really a fair comparison, but aside from that probably the Brain Training series. I believe there was one released for the 3DS but no doubt that completely failed to get off the mark.

As others have correctly pointed out, most of the things you'll find will be Wii/DS titles really. No major surprises there.
