Or only the steam version get achies?

There' a 'popular achievements' section in the catalogue page, but they're not showing up on profile pages, which almost certainly means someone forgot to turn on achievement visibility again. It's an annoyingly common problem with GOG releases. Alexim pointed it out in the release thread, so hopefully a bluetext will notice and sort it out without anyone's having to wait for a support ticket to be dealt with.

Edit: fixed.
