Apologies, but it is the GOG version, not STEAM, not that it makes a difference.
If there is a game I want, I always go to GOG first, and if I can't find it, I grudgingly go to STEAM, lol.
I personally don't like STEAM because they force a "call home" on 99.9% of their games, plus at least 1 of the games I have is several chapters behind (Artemis), and it appears that it won't be updated.
(Oh, a side-note, sometimes the English is a bit off, and I actually have to look it up on the internet. There are some words that actually don't match up, as intended to. Lots of mistakes jumping between British English and American English too.)
