use key on Steam?

[disciple]

I notice this is on Steam.

I don't know how straightforward this is but can we make it so it's possible to use a standard Llamasoft Gridrunner Revolution key on Steam?

I've managed to add all my Humble Bundle stuff into Steam, it'd be cool if I could ad GR to it too.

Cheers

Necroing this thread...

I got GRR when it game out (bought it from the website) so I'm curious if there is some method to add it to steam? Or would I have to re-purchase?

Is this what you want?

If not, it's still on Steam and only £5.99:
