What's combat like? Is it just 'click click click" with the mouse? WASD controls or mouse-click? Any mods or unofficial patches I need to be aware of? I own the game, I just figured it looked kind of dorky and diablo-y, so I decided to strike it off my "to-play" list and put it up for sale. I mean, if you had to choose between the Baldur's Gate series and Divine Divinity, which would you pick? Or Daggerfall vs. Divine Divinity? I can only play so-many 100-hour games in one life-time.
Combat is pretty standard action-RPG point-and-click (game control is mostly point-and-click). The reason I say it's not a Diablo clone is that in contrast to such games, where most of the game other than combat is just a brief set up to "go out into the wilderness/dungeon and kill everything that moves", there's a much greater balance in DD between combat, character interaction, exploration, etc, that is much more in line with the style of open-world RPGs than action-RPGs. Also, since you mentioned that it seemed kind of dorky to you I should mention that the game does have a quirky sense of humor to it- most people I've heard speak about the game viewed this as a positive thing, but some people may not care for it as much. As for comparing it to the BG series, I'd definitely rank BG2 higher than DD, but DD and BG1 are close (I'd probably rank DD slightly higher). The length of DD is also probably closer to 50-60 hours, so while still lengthy it isn't the 100+ hour marathon that some RPGs are.
Personally, I'd take BG. But I played DD on the 360, so it might be completely different on the pc.
Divine Divinity was only released on the PC. You're probably thinking of the sequel, Divinity 2: Ego Draconis (later re-released as The Dragon Knight Saga).
