[Bozos of Bones]

I really like that game. It is a very large world and it's not a barren wasteland, it's actually full of towns and settlements. I love the way you have to do research just to take up a quest, and there are two uber-quests which no one will give you; you'll have to figure them out by yourself. And I was amazed at the fact that for a game so big and free there's only one combination of character-building which will make the game easier. Everything is quite balanced, except for some spells which are misplaced in the school levels(Identify Object is a level 5 spell, which is the last spell level).
As for real-time playing, do not do it. Enemies will get you dead before you can even choose who to attack. I'm not joking, real-time is not hard-it's impossible! Play it in fast-turn-based, you won't be disappointed.
