Rolling up a wizard character is a very difficult task. There a huge number of details to work out. Performing even the most basic of min-maxing is tedious at best. Spell lists and books? Nearly impossible without some sort of stack of paperwork.
I revived my Random Wizard generator, a C program I started some ancient ages ago. It rolls up wizards using the classic 4d6 drop lowest method, min-maxes the racial selection, randomly selects the wizard type, and so forth. I will be adding a Spellbook Generator to it at some point, should I get the time.
