Wow, Trine looks so awesome, if they had a Linux version, I'd have bought it right now, after seeing that video on their website. It reminds me of "The Lost Vikings".
Right now I'm actually considering buying it and trying to run it through wine, but probably won't do it, since i hate running software through wine.
I really hope that LGP is gonna port it.
None of Svartalfs business i guess, since LGP is already porting Shadowground.
