Why am I making these recommendations to you? Because of what you posted concerning how you have gained an appreciation regarding the inherent value of vancian casting, etc. Not many "get" this, they think it's something done out of tradition or what-have-you, but it is a more sophisticated form of gameplay in the context of RPGs than having mana pools or the like.
Same goes for resting restrictions, item scarcity, etc. Obviously Wiz-type games are very different from something like NWN, (first-person view, focus on dungeon/maze exploration), but the real joy comes from the depth of the classes, character advancement, party management, resource management, and making hard decisions as to whether when to rest, when to buy a new shield or instead buy 2 potions of poison removal, etc.
