JoaoPauloZA: Must be a good ol' game because when I leaned English about 40 years ago, prisoning was a very very antiquated archaic term. I prefer imprisonment. I am interested though because it's the same folks who made the Alwa games. I can look past the Swedglish language I guess.
I thought it was one of the weird "cool" made-up words akin to some ordinary one. Like, for example, "the gamering", "the shoppening"... it turns out something that belongs to high end Regency vocabulary, maybe.
