After gaming for 20 odd years, I finally read the Jack Vance stuff and went, MEH. At that point I was very down on the Fire and Forget system. Then I had a breakthrough,
I changed it from Vancian to Amberian.
So now, my wizards in the morning actually cast all of their spells except the last few words and gestures. When they cast the spell, it is not that they forget it, it is that they have to start recasting from the start which is very draining.
For optional rules, I have included:
Hanging spells on familars (extra spells)
Casting as a ritual (1 rd per spell level + temp con drain).
So, Vancian leaves me cold, but I have found a way to embrace fire and forget.
