I'd still go with gog, that way I can choose when I install an update, the updates will be their own separate patches so I can download it and choose when I install it. Also not having the mandatory Steam client just to install the game is very welcome. Games also come with better bonuses on gog most of the time too.

Yes, but in this case DRM is not even a factor to consider, according the Larian even the Steam version is DRM free, the other points still stand however...

Actually, you would have access to the forum regardless, GOG just makes the forums more visible for games that you own.

What didn't you like about Divine Divinity, and how far did you get? If you quit before finishing the Aleroth catacombs I can see not having a favourable impression of the game. The start is pretty heavy on the hack and slash, but there are a few small quests and exploration to do around Aleroth and a certain encounter in the catacombs that give an indication of what the rest of the game will be like. The ending is very combat heavy, as well, but you can bypass most of it, if you are so inclined.

As much as Original Sin draws on Divine Divinity (and Ultima 7) for world interaction, etc, and has similar writing and music, D:OS has a much different combat system, and the quest/story design is much more ambitious. Unless you don't like isometric RPGs in general, or something, not liking DD shouldn't discount D:OS from consideration.

You're absolutely right about the access to the sub-forums, it was wrongly worded on my part.

As for Divine Divinity, it's nothing against isometric RPGs -- in fact, I like those quite a lot --, it's just that I find it boring, grindy, and ultimately not engaging at all. We discussed this in another thread, I appreciate all your efforts for me to enjoy it, but it's just not for me. I will keep trying to get into it, from time to time, out of respect for the person who gifted it, but I honestly haven't been making any progress whatsoever. Perhaps it shouldn't deter me from considering Original Sin, but it was such an underwhelming, disappointing experience, that it actually killed my interest for every other Larian developed title.

Staying on-topic, though, I maintain everything I said: if you're looking for the things you only get from Steam, then get that version of Original Sin. If you prefer GOG's offerings and the whole GOG experience, buy it here, instead.

Ok, I remember that now.

Original Sin isn't grindy, at least. There is less combat and each encounter is specifically placed, rather than an area just being filled with opponents.
