King of the weird games with massively different mechanics, each iteration of the Katamari series was a bizarrely awesome experience that tasked the little prince with rolling up everything to make new stars.
After only a handful of games, the series essentially ended with Beautiful Katamari on the Xbox 360 back in 2007. While Katamari Forever in 2009 did add in some new concepts, it primarily consisted of maps from the previous games, so it was really more a retrospective than an actual new title.
Sadly, there's been just nothing for this generation of consoles (outside a pointless tap-tap mobile game with a vaguely dirty title). No official info has arrived about any sort of real sequels, but there is hope still: Namco registered a trademark for the title Amazing Katamari Damacy earlier this year and also bought the domain to a similarly named website. We may be getting a new Katamari game sooner rather than later!
