I find that I am really loving Divine Divinity...it has it all. Great storyline, fun quests, easy to figure out navigation and controls. I never played the game when it first came out, so for me it's a whole new experience.
For me, the sign of a good game is one that allows for complete and total procrastination when it comes to everything else I should be doing. Divine Divinity does that, in spades. All in all, just a good, fun game.
