The Next Campaign

Once again, I'm pondering the next campaign. I generally try to work about 8 months in advance, so I have plenty of time to prepare - the current campaign has a long way to go anyway.

I've been musing about house rules, as always, and am considering the following:

• Wizards don't need to spend money to add spells to their spellbooks. The great strength of the wizard is versatility, and being able to freely add spells will increase this. However, the wizard will still need to get access to those spells, and so may have to find other spellbooks, or pay other wizards for access to their spellbooks, before adding spells.
• Mundane ammunition won't be tracked. Nor will bar fees, encumberance, and so on. I honestly don't think such things really help the game any. If I were running a low-fantasy game of struggling heroes, this would be different, but I won't be. Of course, this only applies to mundane ammunition - masterwork and magical equipment will need tracked.
• Equipment is sold for half its market price. This is actually the rule as written, which I misread as applying to mundane equipment only.

The use of supplements will depend entirely on the circumstances of the game, of course. In the event that I am not hosting the game, it would be a matter of core rules only. If I were to be hosting the game, a select few carefully chosen supplements would be permitted (most likely Arms & Armour 3.5 (in part), the Complete Book of Eldritch Might, the Book of Iron Might, and the Expanded Psionics Handbook).

Any thoughts?

One more thing...

My last word on customising characters (unless someone raises a counter-argument):

The biggest way of customising characters has absolutely nothing to do with ability scores, feats, weapon choice, or anything else. The biggest and best way to customise a character (of any race, class or level) is through background and role-playing. If your 8th level Paladin has exactly the same skills, feats, weapons, armour and deity as Bob's 8th level Paladin, but one was a priviledged son of the nobility, raised with the constant knowledge that he was destined for righteousness and glory, while yours is a former slave boy, embittered by the loss of his family in a war perpetrated by selfish nobles, and reluctantly given the mantle of paladin by a deity who needs a champion, I suspect that you will see markedly different characters in play.

Unless, of course, you're playing the game purely as a video-game in which case, do you really care that your characters are essentially the same?
