The latest one I can think of is Uncharted. After coming from U2, they tried to focus more on multi-player than single-player for U3, then they went and gave it to Bend for the Vita and they didn't even incorporate it in. Then they make a card game about it..... WUT?? Sony needs to make that second studio at ND release their footage of U4 soon otherwise I will just give up on it like with the Jak series.

I also think that the transformers games have been a little mishandled with so much greatness from after War of Cybertron, High Moon made that movie tie-in game that sucked, then they had a total sales flop with Fall of Cybertron, and then released that weird transformers game based on the new TV show. I hope that they can revive this games series somehow.

I would say Tony Hawk as well, but that skateboard peripheral made babysitting easy.

- Ratchet and Clank
- Colin McRae -> DiRT
- Sim city
- Age of Empires (killed of with freemium attemp)
- MS flight simulator (killed of with freemium attempt)
- Burnout (Burnout crash, really....)
- Silent Hill
- Driver

I did enjoy the latest of Silent Hill and Driver, still a long way from the height of each series.

The most correct answer is Guitar Hero. From 8 figures to nothing in 3 years.

Yay! 

Pretty much anything from Sega not named Virtua Fighter.

Yep, Guitar hero fell about as fast as any franchise I've seen.  They did it to themselves tho by completely oversaturating the market.

banjo kazooie in recent memory

Wild Arms. Where art thou?

I'll also add Star Ocean and Valkyria Chronicles.

Star Fox. Such a bizarrely mismanaged franchise. They cancelled star fox 2 for some reason, star fox 64 was great, and then they just decided to do terrible weird things with the franchise from there.

This year? Devil may cry.
