Indeed, it's been 8 years ago already. But as far as I know, that digital download release was OS4-only (beside the Windows/Mac releases, that is). The MorphOS (and AROS) version was only released with the boxed version of the game a whopping 4 years later. So one could say that at least the MorphOS and AROS versions are somewhat recent ;-)
