Well, someone probably knows.
But not us
Friendly skateboarding gameOlliOlli Worldand its rollerskating gun friendRollerdromehave been delisted on Steam for unknown reasons.
The same thing appears onthe Rollerdrome page.

No, we’re not sure why.
Buckle up, there are layers of ownership here.
The skating games were developed by Roll7 and published under Private Division.
That presumably includes the works of Roll7 published by Private Division, OlliOlli World and Rollerdrome.
The previous games in theOlliOlliseries are still available - they were published under Devolver Digital.
And it’s possible the missing games will be relisted once the dust settles.
It would be a shame otherwise, considering OlliOlli World wasso good it gave me blisters.
And Rollerdrome was a similarblast of adrenaline.
