The NWN dev team made the sorceror too powerful by allowing the "unlearning" of a spell. This lack of flexibility of a sorcerer is supposed to be the drawback for the ability to cast MORE spells.

Prior to modifiers:

At 20th level a Sorcerer can cast 60 spells, including cantrips. At 20th level a Wizard can cast 40 spells. But the wizard can KNOW an infinite number of spells (in theory, but not in practice as you would need an infinite number of monkeys to transcribe them...).

Thus, the Wizard is POWERFUL due to his FLEXIBILITY and the Sorcerer is POWERFUL due to his ABILITY.

The game took away much of the downside of the Sorcerer by giving the PC the ability to erase selection mistakes. Thus, some game mechanic imbalance occured because the sorcerer now has some additional flexibility.

For example, Sleep is a good spell in the early levels, against weak opponents, while Magic Missile starts as a weak spell but increases in power in the mid-levels.

By being able to replace Sleep with Magic Missile, you're losing the consequences of your intial choice. i.e., you have chosen a powerful early game spell that becomes useless by mid-game. You then dump it in favor for a weak early-game spell that increases in power and becomes useful in the mid-game.

I understand WHY the dev. team took this route. Too many players are not going to be DnD players and rather than have a bunch of whining power-gamers trash their game in the forums, they'll put up with a few hard-core gamers who, if they play the game in their "hard-core" way, won't take advantage of this "loop-hole."

As far as the original question goes, I prefer a Wizard. Even with the dev team "loop-hole," the Wizard is still more flexible than the sorcerer and (not discussed in above) gets to higher level spells ONE LEVEL SOONER than the sorceror (on the odd level, not the even). This allows for greater multi-classing opportunities, especially with Rogue, Ranger and Fighter class skill-sets.
