Not a deal breaker (I already bought the game and intend to keep it regardless) but are achievements going to be added to the GOG version of the game?
I know it's probably not a priority and from stuff I heard from other devs the GOG system can be quirky but it would be nice.

I agree. Please devs, give us GOG achievements.

I second that. Not a deal breaker, but definitely it would be nice to have achievements.
