I thought Arcanum was an excellent game - certainly it belongs amongst the greats but I would invite you to experience this game on its own merits. The beauty of Divinity is that it is redefining what a tactical isometric RPG can accomplish and the types of battles you can have. Arcanum, while fantastic from a story and roleplay perspective belongs to a much older genre of more simplistic rpg's that had a more limited sense of tactical and combat possibilities.
Although you are welcome to use the creator to re-make Arcanum using this engine and I think you would have a much better game if you did that.
Cheers!
